Server changes for client mode streaming:
- POST /api/item/ now streams body via async channel → ChannelReader
→ save_item_raw_streaming when compress=false or meta=false
- Add POST /api/item/{id}/meta endpoint for client-side metadata
- Add save_item_raw_streaming<R: Read> to SyncDataService
- Add add_item_meta to AsyncDataService
Fix pre-existing issues that were hidden behind swagger cfg gate:
- Remove #[cfg(feature = "swagger")] from item module so it compiles
with just the server feature
- Fix parse_comma_tags usage (returns Vec, not Result)
- Fix TextDiff temporary value lifetime issue
- Fix io::Error::new → io::Error::other
- Fix ok_or_else → ok_or for Copy types
- Inline format args throughout server code
- Fix empty line after doc comment in pages.rs
- Add cfg_attr for unused_mut where mcp feature gates mutation
- Add type_complexity allow on create_auth_middleware
- Distinguish task error vs save error in spawn_blocking handlers
