fix(ratchet,#1405): cover AI server cognition shims

[joelteply]

Summary

• expand the Lane F TS cognition ratchet to cover src/system/ai/server
• refresh the baseline to include AIDecisionLogger.ts and AIDecisionService.ts after feat(cognition,#1385): generate_response PR-3 — TS shim + delete dead TS (PR-4 folded) #1402
• add a regression test proving AIDecisionService.ts growth fails the ratchet

Validation

• scripts/ratchet/persona-ts-ratchet.sh check
• scripts/ratchet/test-persona-ts-ratchet.sh (9/9 passed)
• precommit: TypeScript compilation passed; browser tests skipped because JTAG/core IPC were not reachable
• pre-push: TypeScript clean; ESLint baseline ratchet held; no Rust-relevant changes so Rust compile/tests skipped

Closes #1405
