- Reject dotted tool identifiers during registration and remove alias-backed lookups.
- Drop web.search compatibility, normalize all code/tests around the canonical web_search name, and update consent/session logic.
- Harden CLI toggles to manage the spec-compliant identifier and ensure MCP configs shed non-compliant entries automatically.
Acceptance Criteria:
- Tool registry denies invalid identifiers by default and no alias codepaths remain.
Test Notes:
- cargo check -p owlen-core (tests unavailable in sandbox).
