chore(version): bump 0.7.0rc2 → 0.7.0rc3

[cipher813]

Summary

3-line version bump rolling the test-trio into a soak-substrate release:

• test(tools): all-tools integration round-trip canary (follow-up to #157) #158 — every-MCP-tool integration canary (Python-level)
• ci(server-extras): [server]-only matrix + layer3 --exercise-all-tools #159 — [server]-extras CI matrix + layer3 --exercise-all-tools (deployment + Fly-level)
• test(coverage): enforce ≥80% coverage + README badge — 86% baseline #160 — coverage gate at 80% + README badge (86% baseline)

Composes with the prior 0.7.0rc2 features (NLI-based contradiction detection, dry_run flag). After PyPI publish + Fly redeploy, this is the version operators should run the Phase 1 standing-tier soak on per Brian's "all known bugs fixed before soak" standard.

Mirrors the PR #77 / #86 / #128 / #156 3-line bump pattern.

Post-merge ritual

1. git tag v0.7.0rc3 && git push origin v0.7.0rc3
2. gh release create v0.7.0rc3 --notes-from-tag --prerelease
3. python -m build → dist/mnemon_memory-0.7.0rc3.{tar.gz,whl}
4. twine upload dist/mnemon_memory-0.7.0rc3* (operator hands — auto-mode classifier blocks; happy to retry if a permission rule has since been added)
5. mnemon upgrade web --app-name mnemon-memory --mnemon-version 0.7.0rc3 (operator — Fly auth)
6. mnemon doctor 7/7 verify
7. Optional: scripts/promote_stable.sh layer3 --exercise-all-tools against a test Fly app (~15 min, validates the new Fly-level probe end-to-end on a real upgrade)

Then soak

1. From claude.ai / Desktop: memory_demote 131 + memory_demote 2402 (clean the standing-tier set per the 8:38 AM audit)
2. memory_list_standing → expect 3/15: #2543 + #2401 + #2084
3. In a fresh terminal: export MNEMON_STANDING_TIER_ENABLED=true
4. Fresh Claude Code session → confirm ## Standing context (always-on; …) sub-section is present
5. Begin ≥1 week soak

Test plan

• mnemon --version returns 0.7.0rc3
• Full suite 855 passing
• Coverage 86% (above the new 80% CI gate)
