Subject: [PATCH] feat(mcp): curated exclude list for cloudflare + glob tool
 filters + default_excluded manifests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cloudflare entry's 3,320-endpoint surface is ~43% product families a
personal/dev account never touches (Zero Trust org-fleet suite, Magic
Transit/WAN, Cloudforce One, Radar analytics, API Shield, legacy
migration surfaces). Ship a 34-pattern curated exclude list in the
manifest: 3,320 -> 1,905 tools kept, and everything Cloudflare adds
later stays enabled by default.

Mechanism, two small extensions:
- tools/mcp_tool.py: tools.include/exclude entries containing glob
  metacharacters now match via fnmatch (plain names stay exact-match),
  so a product family is one pattern instead of hundreds of stale
  literals.
- hermes_cli/mcp_catalog.py: manifests may declare
  tools.default_excluded (mutually exclusive with default_enabled);
  install writes it to tools.exclude and skips the probe/checklist —
  a 3,320-row curses checklist is not a UX. Prior user include
  selections still win on reinstall.

Verified by replaying the real filter functions over the live-probed
3,320-tool list: 1,415 excluded, zero overmatch against a per-product
target audit; DNS/Workers/R2/D1/tunnels/Access/AI kept.
