chore: relicense plugin from GPL-2.0-or-later to GPL-3.0-or-later

[jackgranatowski]

Summary

• Updates the plugin's license declaration from GPL-2.0-or-later to GPL-3.0-or-later across every artifact that names it: plugin headers (slashed.php, slashed-bricks.php, slashed-gutenberg.php), readme.txt, the shipped license.txt, the repo root LICENSE, composer.json, and package.json.
• license.txt and LICENSE now contain the canonical GPL-3.0 SPDX text, each followed by a third-party notice stating the bundled SLASHED framework remains MIT-licensed (GPL-compatible).
• Fixes the Bricks integration README, which incorrectly claimed the integration itself was MIT — it's GPL-3.0-or-later as part of the plugin, with the bundled framework CSS noted separately as MIT.

Context

Split out of #137, which bundled this relicense together with an unrelated admin-app build fix and marketing copy drafts. The admin-app fix has since landed on main independently and needs no separate PR; see #[marketing-copy PR] for the copy drafts.

Test plan

• Confirm GPL-3.0-or-later is the intended license (vs. GPL-3.0-only) — already discussed and confirmed in the original PR thread
• Spot-check license.txt and LICENSE render correctly and the third-party MIT notice is present in both

Warning

Review limit reached

@jackgranatowski, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 56 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

High-Level Assessment

The following are alternative approaches to this PR:

1. Adopt REUSE/SPDX file layout (LICENSES/ + SPDX headers only)

• ➕ More standardized license compliance tooling support
• ➕ Avoids duplicating full license text in multiple places
• ➖ May be less aligned with WordPress plugin distribution expectations (license.txt is common)
• ➖ Would require reorganizing files and updating contributor/docs guidance

2. Separate third-party notices into NOTICE/THIRD_PARTY file

• ➕ Keeps LICENSE/COPYING purely the project license text
• ➕ Makes third-party attribution easier to expand over time
• ➖ Another artifact to keep in sync with distributions
• ➖ Some users expect third-party info co-located with the license text

3. Split non-license deltas into a separate PR

• ➕ Keeps this PR narrowly scoped to legal/metadata changes
• ➕ Reduces risk of unintentionally shipping version/CSS ref/dependency changes
• ➖ More PR overhead if those changes are intentional and already reviewed elsewhere

Recommendation: The overall approach (update all license declarations + ship canonical GPLv3 text + explicitly call out MIT-bundled framework) is appropriate for clarity and compliance. The main item to re-check is scope drift: the PHP entrypoints and manifests also change versions/CSS refs and remove tooling entries (phpunit, npm check script) plus drop a require_once for color-math. If those are unintentional, split or revert them; if intentional, explicitly call them out in the PR summary to avoid surprises.

1. Gutenberg missing color-math include ✓ Resolved 🐞 Bug ≡ Correctness

Description

slashed_gutenberg_require_data_classes() no longer loads includes/class-color-math.php, but
Slashed_Color_Resolver calls Slashed_Color_Math and will fatally error when the Gutenberg
inventory resolves color hex maps.

Code

SLASHED-for-WP/integrations/gutenberg/slashed-gutenberg.php[R170-174]

function slashed_gutenberg_require_data_classes() {
	require_once SLASHED_GUTENBERG_PATH . '../../includes/class-css-parser.php';
-	require_once SLASHED_GUTENBERG_PATH . '../../includes/class-color-math.php';
	require_once SLASHED_GUTENBERG_PATH . '../../includes/class-color-resolver.php';
	require_once SLASHED_GUTENBERG_PATH . 'includes/class-inventory.php';

PR #146 previously re-added class-color-math.php include in Gutenberg/Bricks bootstraps to avoid
fatals.

PR-#146

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The Gutenberg bootstrap requires the resolver but not the math class; the resolver calls
Slashed_Color_Math, and the inventory uses the resolver to build hex maps, so a missing include
can crash at runtime.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
The Gutenberg integration loads `class-color-resolver.php` without loading `class-color-math.php`, but the resolver uses `Slashed_Color_Math`. This can produce a runtime fatal error.

### Issue Context
`Slashed_Inventory` calls `Slashed_Color_Resolver::resolve()` / `resolve_dark()`, which in turn calls `Slashed_Color_Math::*`.

### Fix Focus Areas
- SLASHED-for-WP/integrations/gutenberg/slashed-gutenberg.php[170-174]
- SLASHED-for-WP/includes/class-color-resolver.php[188-200]

### Suggested fix
Add back:
- `require_once SLASHED_GUTENBERG_PATH . '../../includes/class-color-math.php';`

Either in `slashed_gutenberg_require_data_classes()` (preferred, mirrors previous behavior) or by making `class-color-resolver.php` explicitly require its dependency.

### Suggested fix
Choose one:
1) Restore PHPUnit:
  - Re-add `phpunit/phpunit` to `require-dev`
  - Re-add the `"phpunit": "phpunit"` composer script
  - (If applicable) keep `config.platform.php` pinning the project’s PHP floor
2) If PHPUnit is intentionally being removed:
  - Update `.github/workflows/ci.yml` to stop calling `composer phpunit`
  - Remove/adjust other PHPUnit-related artifacts (e.g., docs, config) accordingly.

3. npm run check script removed ✓ Resolved 📘 Rule violation ≡ Correctness

Description

The root package.json no longer defines a check script, so npm run check is unavailable and
workflows that still invoke it will fail with “Missing script: check”. This removal breaks the
required compliance gate that depends on npm run check acting as a read-only drift detection for
stale generated artifacts.

Code

package.json[30]

-    "check": "node scripts/check.js",

Relevance

⭐⭐⭐ High

PR #146 added scripts/check.js and restored package.json "check" script as a drift gate; removal
would break workflows.

PR-#146

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

PR Compliance ID 1543078 requires npm run check to exist and function as a read-only drift check
that fails when generated artifacts are stale. The change removes the check entry from the
package.json scripts block, even though CI/workflows still run npm run check, which will
therefore fail due to the missing script; the repository still contains scripts/check.js,
indicating there is an intended implementation that is no longer wired up via the standard npm
entrypoint.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Reintroduce the `check` npm script entrypoint in the root `package.json` so `npm run check` exists again and serves as the required read-only drift detection gate; this also prevents CI/workflows that invoke `npm run check` from failing with a missing-script error.

## Issue Context
Compliance (PR Compliance ID 1543078) requires `npm run check` to be present and to act as a read-only drift check that fails on stale generated artifacts. The repository still includes `scripts/check.js` as the intended implementation behind `npm run check` (using `--check`-style behavior), and at least one workflow continues to invoke `npm run check` (e.g., the framework sync workflow), but removing the npm script breaks both the standardized entrypoint and the workflow execution.

4. CSS ref version drift ✓ Resolved 🐞 Bug ☼ Reliability

### Issue description
The repo now claims the bundled framework CSS is `v0.6.33`, but the shipped CSS bundles identify as `v0.6.34`. The verifier enforces equality.

### Issue Context
`scripts/verify-sync.js` reads the version from the first line of each `dist/slashed.*.css` and expects all `SLASHED_*_CSS_REF` defines to match `v<distVersion>`.

### Suggested fix
Pick one consistent version:
1) If the bundled CSS is intended to remain `v0.6.34`, revert all three constants back to `v0.6.34`.
2) If the constants are intended to be `v0.6.33`, regenerate/replace `SLASHED-for-WP/dist/slashed.*.css` to `v0.6.33` (typically via the framework sync tooling) and re-run `npm run verify`.
