Release: upgrade bundled SQLite to 3.53.0 (#6900)

[nesquena-hermes]

CHANGELOG stamp for #6900 (@qxxaa), merged in 1aab1e4. Docs-only.

Compiles SQLite 3.53.0 from source in the Docker image to fix the WAL-reset corruption bug. Gate: SHA-256 pinned + independently verified, Codex caught a dropped-SQLITE_SECURE_DELETE data-privacy regression which I fixed (CPPFLAGS + build-time PRAGMA secure_delete==1 assertion, Co-authored @qxxaa); Docker image build + all 3 container smoke tests green.

Tagging exp-v0.52.227.

Greptile Summary

This docs-only release commit adds the changelog entry for the bundled SQLite 3.53.0 Docker upgrade.

• Documents the WAL-reset corruption fix.
• Records checksum verification, enabled SQLite extensions, build-tool cleanup, and preserved secure-delete behavior.
• Limits the stated impact to the Docker image.

Confidence Score: 5/5

The PR appears safe to merge because it only adds an accurate changelog entry for behavior already present in the release tree.

The documented SQLite version, integrity verification, compiled extensions, secure-delete configuration, build assertion, and cleanup behavior match the existing Docker implementation.
