chore(release): 0.5.0

[bompus]

Set core, npm relay and MCP registry metadata to 0.5.0 and finalize the changelog for the 18 commits since v0.4.0.

• New since 0.4.0: Claude Code, Codex, Cursor and OpenAI plugin packages, PRIVACY.md, the exported pause(ms, signal), and the lifecycle fix from fix(lifecycle): recheck waiters only when reconcile changes something #110 that stops a no-change reconcile from rechecking every waiting long poll.
• The fix(lifecycle): recheck waiters only when reconcile changes something #110 changelog entry now says its numbers were measured on a local copy of the server.
• The README performance section now says the historical results were not remeasured for 0.4.0 or 0.5.0. The benchmark workload does not exercise the T3 lifecycle path that fix(lifecycle): recheck waiters only when reconcile changes something #110 changes.
• Removed a stray blank line in the changelog list.

Not included: #96 (guidance change from another session, still open).

Validation: bun run check passes, including the version-drift check.

After this merges: tag v0.5.0 and publish the GitHub release. npm, MCP registry and Glama publication are a separate step.

• README Development checks pass.
• User-visible changes are in the 0.5.0 changelog section.
• No private project names, local paths or credentials are included.
