The clipboard polling thread was detecting programmatic writes (from
paste_and_refocus) as "new" clipboard content and re-inserting them.
Fix: share the last_hash between the polling thread and the paste
command via Arc<Mutex<String>>. When pasting, the Rust command now:
1. Computes the hash of the content being pasted
2. Updates the shared last_hash so the polling thread skips it
3. Writes to clipboard via arboard (moved from JS writeText)
4. Hides window and runs AppleScript paste
This eliminates the JS-side writeText call entirely — clipboard write
now happens in Rust where it can atomically update the hash before
the polling thread's next tick.
