Bruno Postle 5d5b8c6516 tests: extend coverage — SSRF protection, GET endpoint, LRU eviction, branch ref
- SSRF: test local transport rejection, allowlist enforcement, private/loopback/
  link-local IP blocking, allowlist with port, public host permitted without list
- GET /preview: happy path, invalid scheme, local transport rejection
- Tier 2 LRU: eviction at capacity, LRU promotion, cache miss
- git: heads/<branch> ref form (was only tested via HEAD/tag/hash)
- clear_caches fixture now also resets _allowed_hosts between tests

103 → 118 passing tests.
