Release

Re-publish dev to main for v2026.07.15 after reverting the original release PR #557.

CI fix included

• detect SQLite .recover capability through SQLITE_ENABLE_DBPAGE_VTAB
• skip real recovery integration tests on runner images whose SQLite CLI cannot provide .recover
• fail closed on partial .recover output instead of materializing or installing an incomplete database
• add regression coverage for the partial-output failure path

Validation before release

• SQLite storage/offline recovery tests: 87 passed
• isolated CI-equivalent Python suite: 168 passed, 12 platform skips
• Ruff checks passed for all changed Python files
• Frontend lint passed
• Frontend build passed

Supersedes the reverted release PR #557. The fix was merged into dev by #561.
