chore: prepare v1.0.5 release metadata

[Alexander Zaslonov (azaslonov)]

Summary

Prepare v1.0.5 by updating package.json, both root version fields in package-lock.json, and CHANGELOG.md. No dependency, schema, source, or workflow changes are included in this PR.

Release notes cover merged upstream changes: extract/publish tier output and retry reporting (#301), workspace-scoped overrides (#309, #311), product subscriptions (#310), API tag description payloads (#313), WebSocket onHandshake handling (#318), and named-value dependency resolution (#319).

Validation

• Metadata-only diff verified; package and lockfile versions agree; dependencies and schemaVersion unchanged.
• npm ci, build, lint, and Vitest passed on the synchronized release candidate: 63 files, 1,649 tests passed, 2 skipped.
• Built CLI -v, -V, and --version print 1.0.5; npm pack dry run verified 296 files with internal configuration excluded.
• Public release workflow prompt-length check passed. Its existing node --test test/*.test.cjs command succeeds with zero tests because test/ is absent; substantive coverage comes from the Vitest run above.
• Public commit is based directly on public main; only three release metadata files changed.

Release Gate

Keep this PR draft until the production npm publication of v1.0.5 is verified. Do not create a public release tag manually: merging this PR lets the existing Squad Release workflow create the annotated tag and GitHub release.
