feat(forum): Implement v4 agent scaffolding and the 6 core agents (#74)

- Updated `pre-commit` hook to use genuine tools (`tree-sitter`, `semgrep`).
- Enhanced `meta_state_manager.ts` to fully write Git Note telemetry on commit.
- Implemented the 6 core agents as per the v4 blueprint: Gatekeeper, Historian, Adversary, Translator, Analyst, and Evaluator.
- Ensured agents respect Git-Native principles, interacting with `.forum/` directories and the `meta-state` orphan branch via standard Deno Commands.
- Addressed all Deno linting rules (no unused vars).
