docs: sync version references across README, RELEASE, and CHANGELOG

[cobusgreyling]

Summary

Fixes version/doc drift between shipped npm packages and repo documentation.

• README: loop-audit v1.6, loop-init v1.3, link to Discussion Community week — loop-worktree npm, MCP quickstart, tool appendices #219, "All npm CLIs" wording
• docs/RELEASE.md: expand from 6 → 8 packages (loop-worktree, goal-audit), current tag examples and verify commands
• loop-audit CHANGELOG: add 1.6.0 (governance scoring) and 1.5.3 (contributor CTA) entries
• loop-audit README: signals section v1.6+
• loop-audit package-lock.json: sync to 1.6.0
• RELEASE_NOTES_DRAFT.md: loop-audit 1.6.0, CI Sweeper story, updated package table
• STATE.md: link to RELEASE.md instead of hardcoded tag list

Test plan

• Grep confirms no stale v1.5 / v1.2 / six public references in docs
• tools/loop-audit/package-lock.json version matches package.json (1.6.0)

Loop Readiness Audit

Score: 100/100 (L3)

Strong loop readiness — good candidate for L3 with explicit gates.

No suggestions — looking good.
