feat(forum): add missing Gen 1 & Gen 2 PoCs with strict constraint enforcement (#69)

This commit implements the missing Proof of Concepts (PoCs) required by the `agent-forum-v4` architecture blueprint as identified in `CONCEPTS.md`. Updates include: - `execution_flywheel_poc.ts`: Implemented mock version (Gen 1) using in-memory state and physical version (Gen 2) utilizing actual file I/O tracking to prove state management bounds. - `tool_sandbox_poc.ts`: Implemented mock version (Gen 1) yielding simulated telemetry and physical version (Gen 2) utilizing real production-grade tool invocations (Semgrep via CLI and Tree-sitter via WASM module). - `git_hooks_poc.ts`: Implemented mock version (Gen 1) intercepting simulated events and physical version (Gen 2) configuring a physical Git temp directory executing native `.git/hooks/pre-commit` hooks. - `BOUNDARIES.md`: Documented explicit technical boundaries in both `poc-g1` and `poc-g2` to enforce strict isolation vs production file-system operation. - Fixed Deno Linting constraints across `poc-g2/` scripts. - `CONCEPTS.md`: Status flags updated to ✅.

+# Generation 1 Constraints: Mocked, Isolated, In-Memory
+
+The Proofs of Concept (PoCs) in this directory (`forum/poc-g1/`) are bound by strict Generation 1 constraints:
+
+1.  **Isolation:** They must have absolutely minimal effect on the broader repository.
+2.  **Mocked Data:** They simulate interactions (e.g., via simple logic or static JSON returns) rather than executing heavy external binaries or writing to persistent disk.
+3.  **In-Memory State:** They operate predominantly in memory, validating the mathematical and logical feasibility of the concepts (e.g., dependency traversal, state machine bounds, semantic match simulation) without requiring a complex production environment setup.
+
+These scripts validate the *theory and logic* of the architectural blueprint before scaling up to physical implementation constraints.

+# Generation 2 Constraints: Production-Grade Tooling, Physical Limits
+
+The Proofs of Concept (PoCs) in this directory (`forum/poc-g2/`) are designed to prove the physical feasibility of the architecture using **actual, production-ready tools**.
+
+1.  **No Faking:** We are explicitly not faking or mocking tools "to save on repo bloat." If the architecture calls for Tree-sitter or Semgrep, these PoCs must demonstrate their execution using actual binaries or WASM payloads.
+2.  **Physical File I/O:** These scripts interact with the actual filesystem (e.g., tracking states via real JSON files, parsing real Markdown or YAML, dynamically creating physical temp Git repos) to prove constraints.
+3.  **Architectural Validity:** If a required tool is too heavy or fundamentally incompatible with the Local-First/Git-Native bounds (as proven in the Graveyard PoC), it must be flagged for architectural reevaluation. The ability to run the real tool locally is the core pass/fail criterion of Gen 2.
