feat: add codebase genome diff script for structural change detection

Introduces genome_diff.py — a tool for detecting structural changes between
two git refs: file-level changes, function/class signature modifications,
and dependency import changes.

Addresses #132.

+Codebase Genome Diff — Detect structural changes between two versions.
+
+Compares two git refs (commits, branches, tags) and produces a human-readable
+report of structural changes:
+  • Added/removed/renamed files
+  • Changed functions/classes (signature modifications)
+  • New dependencies (imports, requirements, etc.)
+
+Usage:
+    python3 scripts/genome_diff.py --ref1 <commit1> --ref2 <commit2>
+    python3 scripts/genome_diff.py --ref1 main --ref2 feature-branch
+    python3 scripts/genome_diff.py --ref1 v1.0 --ref2 v2.0 --output report.txt

-Test Generation Orchestrator — 3.10 (Compounding Intelligence)
-
-Implements a continuous pipeline that:
-  1. Maintains a queue of repositories to process.
-  2. Runs all 9 test generators per repository.
-  3. Stores results (tests written, pass rate, coverage delta).
-  4. After processing all repos, checks for new code changes and re-queues.
-  5. Runs continuously — never idle (loop with sleep).
-
-Usage:
-  python3 scripts/test_generation_orchestrator.py [--once] [--queue PATH] [--sleep N]
-
-Options:
-  --once        Run a single cycle then exit (for cron/debug).
-  --queue FILE  Path to queue file (default: test_queue.txt at repo root).
-  --sleep N     Sleep seconds between cycles (default: 3600).
