unkinben 8fe4bac2b9 feat: add check_mutable_updates flag for conditional upstream revalidation
When check_mutable_updates: true is set on a remote, expired user-defined
mutable files are revalidated before re-downloading:

- On expiry a conditional HEAD is sent with If-None-Match / If-Modified-Since
- 304 Not Modified: TTL is refreshed in Redis, S3 cache is untouched
- 200 / no conditional support: cache is invalidated and file re-downloaded
- Network error: safe fallback — assume changed, re-download

ETag and Last-Modified from upstream responses are stored in Redis under
mutable:meta:<remote>:<hash> (no expiry, cleaned up on re-download or
cache flush). The flag only applies to user-configured mutable_patterns;
built-in package-type defaults (APKINDEX, repomd.xml, Docker manifests)
are always re-fetched unconditionally.

cache/flush also clears mutable:meta:* keys alongside index:* keys.

unkinben ce01a94141 feat: rename include/index patterns to immutable/mutable with per-remote TTL
Replace the include_patterns/index_patterns split with a clearer
immutable_patterns/mutable_patterns model:

- immutable_patterns: artifacts cached indefinitely (no TTL)
- mutable_patterns: artifacts that expire and are re-fetched after
  cache.mutable_ttl seconds (replaces cache.index_ttl)

_PACKAGE_INDEX_PATTERNS renamed to _PACKAGE_MUTABLE_PATTERNS; all
built-in package-type index patterns (APKINDEX, repomd, manifests, etc.)
default to the remote's mutable_ttl (default 1 hour).

cache.file_ttl renamed to cache.immutable_ttl for consistency.
Adds github-archive remote to remotes.yaml as a worked example showing
tag archives as immutable and branch archives as mutable (1-day TTL).

docker-compose.yml: fix VERSION=dev → 2.2.2.dev0 (valid PEP 440),
add :z SELinux label to volume mounts.

unkinben 8da43e610e tests: resolve all peer-review issues across test suite
Address every substantive critique from the peer review:

test_cache: replace tautological same-inputs key test with hardcoded
hash assertion; assert setex call + TTL in mark_index_cached test;
assert client is None for unavailable no-op; rename Packages.gz test
to document intentional behaviour; add alpine sig/tmp negatives; add
hyphenated and date-tag docker positive cases; add key hash-length
assertion.

test_config: replace live-constant comparisons with literal string
assertions for alpine/rpm/docker; add unknown package type test;
add dict-keyed repositories branch coverage (per-repo override and
fallback); fix cache config to full equality check; add explicit empty
index_patterns test.

test_docker_auth: fix case-insensitive test to verify realm value;
add field-order (scope before service) limitation test; add pipe-char
collision documentation test; add missing fetch_token edge cases
(no token field, HTTPStatusError, missing expires_in default 300);
replace rubber-stamp delegate test with end-to-end parse→fetch test.

test_storage: replace split prefix/suffix assertions with structural
3-part check + pinned sha256 assertion; fix Docker blob digests to
64-char hex; add secure=True URL test; add upload return value test;
add download_object 404-on-ClientError test; remove redundant subset
test.

test_routes: add metrics.record_cache_hit/miss assertions; add
mark_index_cached assertion after cache miss on index (docker + generic);
add Content-Disposition, X-Artifact-Size header checks; add rpm/xml
content-type tests; add flush test that verifies Redis keys are deleted
when cache is available; add smoke coverage for upload (PUT), HEAD, DELETE,
/metrics, and /config routes.

unkinben 2d0e2c64e6 feat: add test suite, tox, pre-commit, and ruff formatting
- tests/: 107 unit tests across config, cache, docker_auth, storage,
  and FastAPI routes; all passing under pytest-asyncio auto mode
- tox.ini: runs pytest via uvx --with tox-uv tox (py311)
- .pre-commit-config.yaml: ruff lint + ruff-format at v0.15.12
- pyproject.toml: pytest config (asyncio_mode=auto), ruff config
  (line-length=140), tox/pre-commit added to dev extras
- Makefile: test/tox/pre-commit targets via uvx --python 3.11
- Source files reformatted by ruff-format (no logic changes)
