feat(plapi): stamp from_source=cli on authenticated app creation

[mwickett]

Phase 2 of the CLI Tier 1 attribution plan. Phase 1 (clerk_go#18277) makes POST /v1/platform/applications accept an optional from_source field and persist it to applications.from_source. This PR is the CLI counterpart: every authenticated app the CLI creates now stamps from_source: "cli" so those apps are identifiable in BigQuery dim_applications for growth analytics.

Phase 1 PR: https://github.com/clerk/clerk_go/pull/18277

How

• Export a single canonical CLI_FROM_SOURCE = "cli" constant from packages/cli-core/src/lib/plapi.ts.
• createApplication() includes from_source: CLI_FROM_SOURCE on the POST body. Signature unchanged, so both call sites (clerk apps create and the create-new branch of clerk link) keep working without edits.

Canonical value matches what PR #157 (auto-claim keyless) already sends on its accountless POST body.

Test plan

• Updated plapi.test.ts body-shape assertion.
• Added guardrail test pinning the literal to the exported constant.
• apps/create.test.ts and link/index.test.ts still pass (signature unchanged).
• bun run test green (72 suites).
• bun run format:check, bun run lint, bun run typecheck all clean.
• bun changeset status --since=origin/main — clerk bumps minor.

Rollout

Backwards-compatible. If this ships before Phase 1 deploys, PLAPI silently ignores the unknown field. Once Phase 1 deploys, stamps start appearing in applications.from_source.

📝 Walkthrough

Walkthrough

Adds CLI attribution for applications created via the Clerk CLI. Introduces and exports CLI_FROM_SOURCE = "cli" in packages/cli-core/src/lib/plapi.ts. Updates createApplication(name) to include from_source: CLI_FROM_SOURCE in the POST payload to /v1/platform/applications. Updates the test expectation in packages/cli-core/src/lib/plapi.test.ts to require the new field. Adds a changeset entry documenting the client-side change that requires server-side PLAPI support.
