30c417fe70
Adds security.website_blocklist config for user-managed domain blocking
across URL-capable tools. Enforced at the tool level (not monkey-patching)
so it's safe and predictable.
- tools/website_policy.py: shared policy loader with domain normalization,
wildcard support (*.tracking.example), shared file imports, and
structured block metadata
- web_extract: pre-fetch URL check + post-redirect recheck
- web_crawl: pre-crawl URL check + per-page URL recheck
- browser_navigate: pre-navigation URL check
- Blocked responses include blocked_by_policy metadata so the agent
can explain exactly what was denied
Config:
security:
website_blocklist:
enabled: true
domains: ["evil.com", "*.tracking.example"]
shared_files: ["team-blocklist.txt"]
Salvaged from PR #1086 by @kshitijk4poor. Browser post-redirect checks
deferred (browser_tool was fully rewritten since the PR branched).
