Support flexible A2A agent registration and fix redirects

- Accept direct .json URLs (e.g., http://host/.well-known/agent-card.json)
- Accept base agent URLs (e.g., http://host/a2a/sentinel)
- Extract canonical URL from agent card response
- Try both agent-card.json and agent.json for compatibility
- Follow HTTP redirects for POST requests (fixes 307 redirects)
- Remove trailing slash from POST endpoint to avoid redirect loops
