feat: stabilize multi-env sync, bubble verification, and FFI cache observability

- Add OMNIPKG_DEBUG gated _dbg() helper for zero-cost structured debugging
- Introduce per-version .omnipkg_synced_* markers to prevent redundant interpreter syncs
- Ensure sync markers are written + old markers cleaned across native and threaded sync paths

- Fix uv_ffi version healing:
  - Resolve min version dynamically from pyproject.toml
  - Replace uv CLI calls with python -m pip for reliability
  - Improve version comparison + fallback handling

- Strengthen bubble install verification:
  - Discover all staging dists (no pre-filter) to handle hyphen/underscore mismatches
  - Verify actual installed contents instead of name-locked assumptions

- Fix Redis index consistency:
  - Canonicalize package names before adding to index to prevent duplicate keys

- Improve KB rebuild + repair correctness:
  - Re-fetch index after gatherer.run() to avoid stale reads
  - Add detailed debug visibility for instance discovery, ghost cleanup, and version mismatches

- Add deep FFI cache instrumentation:
  - Snapshot site-packages cache before/after installs
  - Detect and log target install leakage into main cache
  - Propagate is_target flag through FFI results

- Remove unsafe --target subprocess bypass:
  - Route all installs through FFI path with proper isolation guarantees

- Improve tool version detection fallback (subprocess-based when metadata missing)

- Update vendored uv submodule
