tobin 7eebc68699 Tighten policy scan: hook scope, telemetry, disclosure; make blocking
policy/prompt.md — adds Part 2 (hook scope and disclosure):
- Enumerate every registered hook and read its source.
- Flag has_broad_scope_hooks when UserPromptSubmit/PreToolUse/
  PostToolUse runs without a project-relevance gate, or any hook
  reads user data beyond the plugin's stated scope — regardless of
  whether it makes network calls.
- Flag has_undisclosed_telemetry when any hook or shipped code calls
  a non-MCP host without explicit disclosure + opt-out.
- Flag description_matches_behavior=false when the install
  description would not lead a reasonable user to expect the
  hooks/telemetry/data-access found.
- passes=false when any of the above trip. Violations must cite the
  specific hook/file and what the user wasn't told.

The bar is now "handles user data responsibly," not merely "isn't
malicious." A non-malicious plugin that observes more than its stated
purpose justifies will fail.

policy/schema.json — adds required hooks[], has_broad_scope_hooks,
has_undisclosed_telemetry, description_matches_behavior.

scan-plugins.yml:
- fail-on-findings: true (blocking — loosen later if FP rate too high)
- workflow_dispatch with scan_all input for full re-review of all
  external entries
- timeout-minutes: 360 (full scan of 117 entries at ~96s each ≈ 3h)
- trigger on .github/policy/** so prompt edits get scanned
