Replace Python agent with claude -p CLI

[xrendan]

Summary

• Eliminates the Python agent entirely — removes agent/src/, pyproject.toml, claude-agent-sdk, psycopg2, and the in-process MCP server
• Rails jobs now spawn claude -p directly; Claude reads data via curl to new Rails GET endpoints and writes via existing endpoints
• WebFetch restricted to *.canada.ca, *.gc.ca, www.parl.ca

What changed

New Rails API (read endpoints):

• GET /api/agent/commitments/:id — full commitment with criteria, matches, events, bills, departments, status_changes
• GET /api/agent/commitments — list with filters (status, policy_area, stale_days, limit)
• GET /api/agent/commitments/:id/sources
• GET /api/agent/bills/:id + GET /api/agent/bills
• GET /api/agent/entries/:id + GET /api/agent/entries?unprocessed=true

New tracking endpoints (called by Stop hooks):

• PATCH /api/agent/commitments/:id/touch_assessed — updates last_assessed_at; skips if a recent evaluation_run already exists
• PATCH /api/agent/entries/:id/mark_processed — sets agent_processed_at; idempotent

Stop hooks (agent/.claude/hooks/):

• on_stop_commitment.sh — fires after every commitment evaluation run
• on_stop_entry.sh — fires after every entry processing run
• Hooks are injected per-job via --settings JSON, so each job type only loads its own script

Jobs:

• Stream claude -p output to stderr in real time via popen2e
• Pass CLAUDE_CODE_OAUTH_TOKEN for auth; explicitly unset RAILS_MASTER_KEY and SECRET_KEY_BASE
• Per-job hook config passed inline via --settings

Other:

• Migration: add_column :entries, :agent_processed_at, :datetime
• CORS: allow all localhost:* origins in development
• Dockerfiles: install claude CLI binary

Test plan

• Tested against commitment #2881 — agent evaluated successfully, criteria assessed, evaluation run recorded
• Run bundle exec rails db:migrate
• Verify GET /api/agent/commitments/1 returns expected shape
• Queue an AgentEvaluateCommitmentJob and confirm last_assessed_at updates
• Queue an AgentProcessEntryJob and confirm agent_processed_at is set
