fix(core,fs-watcher,daemon): isolate FFI ops, eliminate false FS signals, and restore deterministic daemon boundaries

- Core (FFI path):
  - Hoisted `_is_target_call` detection to ensure `finally` block safety
  - Prevented daemon START/END signaling for `--target` installs (bubble isolation)
  - Fixed incorrect FS watcher signaling that caused spurious invalidations during temp installs
  - Ensured op marker lifecycle is always cleaned up, even on failure paths
  - Reduced noisy stderr prints → consistent debug logging via `_dbg`

- FS Watcher:
  - Eliminated false-positive invalidations by ignoring non-package FS noise (locks, cache, pycache)
  - Added strict validation: only `.dist-info` events are considered authoritative package changes
  - Introduced silent fast-path when no relevant events occurred (removes log spam)
  - Improved external change detection with explicit culprit attribution
  - Added per-path logging context for multi-env clarity
  - Removed redundant/duplicate INFO logs during op lifecycle
  - Added watcher process identity logging (PID + python exe) for debugging multi-daemon setups
  - Refined patch pipeline: only triggers invalidation on real package deltas

- Daemon:
  - Removed premature FS watcher thread startup (eliminates race conditions during init)
  - Ensured watcher lifecycle aligns with actual daemon execution context

- System-level impact:
  - Fixed cross-contamination between bubble installs and main environment
  - Eliminated incorrect cache invalidation during internal operations
  - Restored deterministic FS event → package state mapping
  - Dramatically improved signal-to-noise ratio in logs
  - Enabled clean, traceable operation lifecycle (START → validated → END)

Result:
  Clean, high-fidelity logs with zero false positives, accurate package attribution,
  and fully isolated operation boundaries across FFI, daemon, and filesystem layers.
