merge: sync docs-v2-dev into docs-v2

[DeveloperAlly]

Description

Syncs docs-v2-dev into docs-v2, treating docs-v2-dev as the source of truth for docs content, navigation shape, scripts, workflows, cleanup, and docs.json. Fixes two GitHub Actions workflow correctness issues in generate-action-docs.yml identified during review.

Scope

• .github/workspace/actions-library/generators/maintenance/generate-action-docs.yml — fix on.push.branches literal value and guard inputs.dry_run references
• v2/** — content and navigation alignment from docs-v2-dev
• .github/workflows/** — workflow path updates, branch/trigger configuration
• docs.json — navigation shape from docs-v2-dev
• Repo governance artifacts: allowlist, agent rules, stale backups/locks

Out of scope: style-guide and copy-lint violations in existing docs-v2-dev content debt (tracked as follow-up).

Validation

• Passed: node operations/scripts/validators/content/structure/lint-structure.js --check
• Passed: node operations/scripts/validators/governance/compliance/check-agent-docs-freshness.js --json
• Passed: node operations/tests/unit/docs-navigation.test.js
• Passed: node operations/tests/unit/authoring-tools.test.js
• Passed: node operations/tests/unit/mdx.test.js --staged
• Passed: merge commit pre-commit hard gates
• Inconclusive: node operations/tests/integration/mdx-component-runtime-smoke.js brought the scoped server up successfully but did not return a final harness result before manual stop
• Failing on existing docs-v2-dev content debt: node operations/tests/run-pr-checks.js --base-ref docs-v2 reports large style/copy-policy failures across the branch diff, independent of merge-conflict resolution

Follow-up Tasks

• Triage and fix the existing style-guide and copy-lint violations surfaced by PR-scope checks if this branch is expected to merge with a green CI lane.
• Re-run the runtime smoke harness after investigating why the wrapper does not return after the scoped preview server is ready.

Type of Change

• Bug fix (fixes an issue)
• New content (adds new documentation)
• Content update (improves existing content)
• Style/formatting fix
• Information architecture change
• Other (merge integration + workflow correctness fixes)

Changes Made

• Treats docs-v2-dev as the source of truth and merges into docs-v2 via a clean integration worktree (merge commit 4282b5993).
• Removes unauthorized base-side root directories (docs/, tests/) that violated the repo allowlist.
• Removes tracked machine/local artifacts including .claude session state, .codex/locks-local JSON, and docs.json.bak.
• Updates scoped preview navigation configs so their /redirect surface matches the committed docs.json state.
• Removes the obsolete v2/resources/redirect Resource HUB anchor contract and aligns the public Resources tab with the current non-anchor tab model.
• Fixes on.push.branches in generate-action-docs.yml — replaces the unsupported context expression ${{ vars.DEPLOY_BRANCH }} with the literal branch name docs-v2.
• Fixes unsafe inputs.dry_run references in generate-action-docs.yml — computes a DRY_RUN env var once as ${{ github.event_name == 'workflow_dispatch' && inputs.dry_run || false }} and replaces all three inputs.dry_run usages with $DRY_RUN (shell) and env.DRY_RUN (expression context), so push-triggered runs no longer fail when inputs is undefined.

Testing

• Tested locally with npm run dev
• Verified all links work

Additional Notes

The two generate-action-docs.yml fixes ensure the workflow loads and triggers correctly on push events: the on.push.branches field now uses a literal branch name (required by GitHub Actions), and all inputs.dry_run references are guarded so they safely default to false when inputs is not available (i.e., on non-workflow_dispatch triggers).
