fix: AI-created notes now trigger vault refresh and auto-open in tab

Root causes:
- toolInputMapRef in useAiAgent was overwritten by tool_progress events
  (which arrive with input=undefined AFTER the assistant message set
  the full input), causing detectFileOperation to receive undefined
  and skip file creation detection entirely.
- MCP open_note only broadcast open_tab without vault_changed, so
  the note list didn't refresh when Claude Code called open_note.
- detectFileOperation only handled Write/Edit but not Bash commands
  that create .md files via redirects.

Fixes:
- Preserve accumulated input in toolInputMapRef (input ?? prev?.input)
- MCP open_note now broadcasts vault_changed before open_tab
- detectFileOperation now detects Bash redirect patterns (>, >>, tee)
