feat(v0.2.0): comprehensive foundation hardening and test verification

- Finalized Reflection Loop: Injected deterministic rejection traces back into LLM prompts.
- Hardened Actuators: Added path-traversal guards and enforced Merkle snapshots on AST edits.
- Refactored Lisp Utils: Merged validator/repair into a unified utility skill with whitelist Ast-walking.
- Fixed Build: Resolved all 30+ syntax, scoping, and package visibility errors.
- Verified: Full pass (100%) on all 5 core test suites.
