Fix sqlean-extensions, clean up warnings, complete P1 tasks

- Fix pcre2 compilation by removing header from source patterns in build.rs
- Re-enable sqlean-extensions in libsql-server (SQL regex, crypto, etc.)
- Clean up all compiler warnings
- Fix deprecated into_router() warnings
- Update CHANGELOG and MIGRATION_REPORT
- All P1 tasks complete - only H2C and admin dump remain disabled

-### Build Fix
-- Disabled `sqlean-extensions` feature in `libsql-sys` due to pcre2 compilation issue on macOS
-- This removes regexp, crypto, fuzzy, math, stats, text, and uuid SQL extensions
-- Binary builds successfully without these extensions
+### Build Fix - SQLEAN EXTENSIONS RESTORED ✅
+- **Root Cause**: `libsql-ffi/build.rs` was incorrectly including `pcre2_internal.h` as a source file
+- **Fix**: Removed header file from source patterns in build.rs
+- **Result**: All SQL extensions (regexp, crypto, fuzzy, math, stats, text, uuid) now work!
 
 ### Key API Changes
 - `hyper::Body` → `hyper::body::Incoming`
