Vendor cmdr-fsevent-stream into the monorepo

- Move the fork from a git dependency (github.com/vdavid/cmdr-fsevent-stream) to `crates/fsevent-stream/`, added as a workspace member
- Switch `Cargo.toml` dep from `git + rev` to `path`
- Remove `allow-git` entry from `deny.toml`
- Update indexing `CLAUDE.md` to reflect new location

Also a change to fsevent-stream/src/stream.rs which got mixed into this:
- Set channel capacity: 1,024 → 32,768
- Added Arc<AtomicBool> overflow flag to StreamContextInfo and EventStream
- Callback sets overflow flag on try_send failure (logs once, then silent)
- Exposed overflow_flag() on EventStream
