llm-connect agents. Wire into agents-codex.template and claude-md.template.
Add propagate_credential_routing.py for surgical rollout without clobbering
repo-specific AGENTS.md extensions (REPO-AGENTS-EXTENSIONS marker).
Adds preferred workplan REST/event surfaces, legacy-meter telemetry and weekly review summaries, documentation/dashboard terminology updates, dashboard API loading fixes, and close-out sync for STATE-WP-0052 and STATE-WP-0054.
