feat: Implement daemon-only architecture for query operations

This commit implements the daemon-only architecture where all query
operations (functions, strings, decompile, memory, summary, xrefs)
must go through the persistent daemon instead of spawning new Ghidra
processes per command.

Key changes:
- Wire IPC client in main.rs to route queries through daemon
- Add requires_daemon() to determine which commands need daemon
- Add execute_via_daemon() to translate CLI commands to IPC calls
- Deprecate HeadlessExecutor with migration notice
- Fix filter.pest hex number parsing order (hex before number)
- Add #[allow(dead_code)] to infrastructure modules for future use
- Mark E2E tests requiring daemon as #[ignore]

Architecture benefits:
- Faster queries: Ghidra stays loaded, no 5-30s startup per command
- Simpler code: One execution path instead of two
- Better UX: Clear daemon requirement with helpful error messages

When daemon is not running, users see:
  Error: This command requires the daemon to be running.
  Start the daemon with: ghidra daemon start --project <name>
