Commit Message

Add tcrsift data cache + download + auto-fallback (#32) (#33)

* Add tcrsift data download + metadata sidecar (#32 chunks 2+3)

Extends the foundation with automated downloads:

  tcrsift data download                # all supported DBs
  tcrsift data download --db iedb
  tcrsift data download --force        # refresh

Per-DB download support:
  - IEDB: stable URL at iedb.org/downloader.php (zip with tcr_full_v3.csv)
  - VDJdb: dynamic resolution via GitHub releases API for latest release
  - CEDAR: no stable single-file endpoint; --db cedar reports clearly
    and points users at the manual install location

Each downloaded DB gets a _meta.json sidecar recording source_url,
downloaded_at (UTC ISO timestamp), size_bytes, and sha256. Lets users
audit what they're running annotation against.

All HTTP I/O is injectable via `opener=` for hermetic tests. 9 new
tests mock urlopen with in-memory zips covering: successful extraction,
metadata write, skip-when-cached, force-redownload, missing archive
member raises, VDJdb GitHub-API resolution, missing release asset,
CEDAR-has-no-download, and unknown-db error paths.

10 datacache module tests from chunk 1 still pass; 16 + 9 = 25 total
new tests. Coverage on datacache.py is now ~95%.

* Bump version to 0.8.3
