feat: Port all agent-forum-v4 Gen 1 PoCs to Gen 2 using real tooling (#68)

This commit ports the remaining Gen 1 proof-of-concept experiments from `forum/poc-g1` into `forum/poc-g2` while substituting naive mocks with real, production-ready mechanisms.

Key advancements include:
- `code_intelligence_poc.ts` and `cfg_poc.ts`: Swapped regex matching for actual Javascript AST traversal using `acorn`.
- `static_analysis_poc.ts`: Replaced mock payloads with real `deno lint --json` output executed via `Deno.Command`.
- `vector_db_poc.ts` and `multi_vec_poc.ts`: Replaced basic JS arrays with actual `jsr:@db/sqlite` instances utilizing User-Defined Functions (UDFs) to perform native vector cosine similarity queries in memory or on disk.
- `protobuf_poc.ts`: Implemented robust protobuf serialization/deserialization via `protobufjs`.
- Semantic/Governance PoCs (`constitution_poc.ts`, `ontology_poc.ts`, `state_machine_poc.ts`, `orphan_branch_poc.ts`, etc): Replaced string-mock I/O with absolute filesystem reads, real YAML parsing using `jsr:@std/yaml`, and isolated `Deno.Command` Git sandboxes.
- Updated `forum/poc-g2/lab.ts` to orchestrate and execute all 19 experiments, proving 100% test pass rate with Gen 2 tooling.
