- Added sync truncation helpers to recursively prepare session entries and externalize image data. - Reworked session persistence to use synchronous preparation plus `writeSync` with close-state checks. - Added synchronous session-storage APIs and rerouted write paths to `writeLineSync`/`readTextSync`. - Added `BlobStore.putSync`, migrated hashing to `Bun.SHA256`, and updated hash tests accordingly.
