fix(desktop): fix Claude agent spawn from managed runtime and rotate logs on restart

- Always override spawnClaudeCodeProcess to use process.execPath instead of
  SDK's PATH-based "node" lookup, which fails in the managed runtime bundle
- Fix append-mode arg ordering in resolveClaudeSpawnCommand so extra CLI args
  (e.g. --chrome) go after cli.js, not before it (Node exit code 9)
- Rotate daemon.log on every daemon restart for clean startup logs
- Remove dead dev_resource_root fallback from runtime_manager.rs
- Canonicalize current_exe path in CLI runner
