chore(6a2): migrate bot_directives to A2ML, remove deprecated .scm metadata files

Converted .machine_readable/bot_directives/*.scm → *.a2ml (8 files:
echidnabot, finishbot, glambot, rhodibot, robot-repo-automaton, seambot,
sustainabot, README). Content equivalent; format is now A2ML TOML-like
with copyright headers, consistent with 6a2 state files.

Removed echidnabot/TESTING-REPORT.scm (2025-12-29 snapshot, superseded
by STATE.a2ml which is the authoritative state record).

Updated .claude/CLAUDE.md with explicit deprecation rule: any .scm
metadata file found under .machine_readable/ must be converted to A2ML
and deleted. Guix package .scm files are explicitly exempted.

+### CRITICAL: .scm metadata files are DEPRECATED
+
+**All `.scm` state/metadata files have been replaced by `.a2ml`.**
+
+If you find any `.scm` file under `.machine_readable/` (e.g. `STATE.scm`, `META.scm`,
+`ECOSYSTEM.scm`, `AGENTIC.scm`, `NEUROSYM.scm`, `PLAYBOOK.scm`, bot directive `.scm`
+files, or similar), you MUST:
+
+1. Check whether an equivalent `.a2ml` file already exists
+2. If yes — delete the `.scm` file immediately (`git rm`)
+3. If no — convert its content to A2ML format first, then delete the `.scm` original
+
+**Exception:** `guix.scm` files and files under `guix/` or `guix-channel/` are Guix
+package definitions (not metadata files) and must NOT be deleted.
