v0.2.4 — Patch: fix broken export paths, doc corrections

[0.2.4] - 2026-07-08

Fixed

• package.public.json — broken export paths: Three new v0.2.3 exports (./backend/lib/rate-limit, ./backend/lib/api-keys, ./backend/lib/audit) used backend/... paths missing the ./ prefix. Published package would fail to resolve these imports. Paths corrected to ./backend/... to match all other exports.
• docs/API.md — API keys mismatch: Documented expiresIn duration field, but code uses expiresAt ISO 8601 datetime. Docs updated to match actual code behaviour.
• docs/API.md — plugins response shape mismatch: Documented displayName/enabled fields that do not exist in the PluginManifest type. Actual shape is name/version/description. Docs updated to match code.
• docs/PRODUCTION_STATUS.md — route count: Stale count of 14 route files. Actual count is 17 (added keys, plugins, visibility in v0.2.3). Corrected.

Changed

• Version bumped from 0.2.3 to 0.2.4 across all workspace manifests: root package.json, package.public.json, backend/package.json, frontend/package.json, packages/{sdk,cli,mcp-server,db}/package.json, backend/src/index.ts (Swagger), docs/openapi.json, docs/PRODUCTION_STATUS.md.
