When a branch/HEAD fetch fails (network error, auth failure, server down),
_open_remote now logs a warning rather than silently passing. A boolean
is_stale propagates through _get_repo → fetch_ifc so callers know the data
comes from a stale local cache.
The service adds X-Ifcurl-Cache: stale to /preview and /render_diff responses
when stale data was served, so Forgejo or a browser viewer can surface a
warning to the user.

Disk cache (bare repo clones under ~/.cache/ifcurl/):
- IFCURL_CACHE_MAX_GB env var sets the max total size; when exceeded after a
new clone the oldest-accessed repos are removed until under the limit
- remote_url stored per clone entry so ifcurl cache list can show the URL
- _touch_cache() updates mtime on every repo open for LRU tracking
In-memory caches (service.py):
- _T2_MAX and _T3_MAX now read from IFCURL_T2_MAX / IFCURL_T3_MAX env vars
(defaults: 8 IFC blobs, 64 selector results) — configurable without rebuild
New CLI: ifcurl cache list | prune [--max-gb N] | clear
Tests: 6 new unit tests for _dir_size, _touch_cache, _repo_cache_entries,
_evict_if_needed. 118 → 124 passing.

- 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.

- ifcurl/auth.py: token config (~/.config/ifcurl/tokens.json),
get_token_for_host(), inject_token() for HTTPS URL credential injection
- ifcurl/git.py: thread token= through fetch_ifc/fetch_ifc_bytes/_open_remote;
authenticated fetch uses 'git fetch <auth_url> +refs/*:refs/*' so the
token is never written to on-disk git config
- ifcurl/service.py: optional token field in PreviewRequest; request token
takes precedence over config-file token; get_token_for_host imported at
module level for clean monkeypatching in tests
- tests
