feat: enable full shell access for AI agent + simplify MCP tools

Remove --tools "" restriction so the agent has native bash/read/write/edit
access. Set vault path as working directory for the subprocess.

Simplify MCP to 4 Laputa-specific tools (search_notes, get_vault_context,
get_note, open_note) — everything else is handled by native tools.

Add file operation detection from Write/Edit tool calls to auto-open
created notes and refresh modified notes in the UI. Enhanced tool call
labels show bash commands, file paths, and note names.
