chore(release): 3.4.1

[igorls]

Release 3.4.1

Bumps the version across all six version sources (the five version-guard.yml checks plus the README badge that tests/test_readme_claims.py enforces) and promotes the [Unreleased] changelog to ## [3.4.1].

Version sources bumped 3.4.0 → 3.4.1

• mempalace/version.py (source of truth)
• pyproject.toml
• .claude-plugin/marketplace.json
• .claude-plugin/plugin.json
• .codex-plugin/plugin.json
• README.md version badge
• uv.lock (editable package entry)

Shipping in 3.4.1

Features

• Cursor IDE plugin (.cursor-plugin/)
• Cursor IDE hook support (stop / preCompact / sessionStart)
• First-class Antigravity IDE support (+ zero-config interpreter resolution)

Bug fixes

• embeddinggemma bulk re-embed OOM fix
• Backup-retention pruning (max_backups)

CHANGELOG link block

Also restores the compare-link reference block, which had been abandoned at v3.2.0: adds [3.4.1] and the previously-missing [3.4.0], and repoints [Unreleased] at v3.4.1...HEAD.

Pre-existing issues noted (out of scope for this patch)

• 3.4.0 never got its own CHANGELOG section — its notes were promoted retroactively only as a compare-link here; the section body remains undocumented.
• The compare-link block is still missing the [3.3.0]–[3.3.6] chain.

Validation

• All six version sources agree (replicated version-guard.yml locally — green)
• Entry-point alignment check (RELEASING.md) — mempalace-mcp consistent across manifests
• ruff check + ruff format --check — clean
• Full suite: 2853 passed, 5 skipped

After merge (manual, per docs/RELEASING.md)

Merge develop → main, then draft a GitHub Release targeting main with tag v3.4.1 to trigger publish.yml (PyPI Trusted Publishing, manual approval on the pypi environment).

Code Review

This pull request bumps the version of MemPalace from 3.4.0 to 3.4.1 across several plugin manifests, configuration files, and documentation. The reviewer identified an issue in CHANGELOG.md where the newly added compare link references a missing version chain, resulting in broken links, and provided a suggestion to complete the chain.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

The newly added [3.4.0] compare link references v3.3.6, but the [3.3.6] reference link definition (and the rest of the [3.3.x] chain) is missing from the bottom of the file. This results in broken/unclickable version headers in the changelog. Adding the missing compare links completes the chain down to v3.2.0.

Superseded by #1809. This branch is on the release/* pattern, which a repository ruleset protects (pull-request-required + no force-push), so it can't take the changelog review fix as a follow-up commit. #1809 carries the same release bump plus the rebuilt CHANGELOG compare-link chain on an unprotected branch.
