* fix: inject SessionDB into AIAgent for WebUI sessions
session_search tool requires a SessionDB instance passed via the
session_db parameter. The CLI and gateway paths already do this,
but the WebUI streaming path was missing it, causing every
session_search call to return 'Session database not available'.
Initialize SessionDB before creating the AIAgent and pass it through.
Failure is non-fatal — a warning is printed and session_search
gracefully degrades.
* fix: inject SessionDB into AIAgent for WebUI sessions (enables session_search) (#356)
- api/streaming.py: initialize SessionDB() before AIAgent construction and
pass session_db= kwarg so session_search works in WebUI sessions
- tests/test_sprint42.py: 7 new tests covering SessionDB injection, try/except
guard, WARNING log, ordering, and AST lock-safety check
- CHANGELOG.md: v0.50.13 entry; 822 tests total (up from 815)
