feat(sde): bulk-load downloader + offline system/station lookups
Implements issue #51. Adds a Fuzzwork SDE downloader/importer and
expands the offline lookup layer beyond item types.

- sde.py: SDE_URL constant (FAMILIAR_SDE_URL override) and
  async download_sde() that streams + bz2-decompresses the dump
  incrementally to sde_path(), resetting the cached connection.
- sde.py: system_by_id/system_by_name/station_by_id offline lookups,
  all degrading to None when the table/file is missing.
- universe.py: get_system/get_station prefer the SDE when available,
  falling back to ESI otherwise (signatures unchanged).
- __main__.py: `familiar sde download|status|path` subcommands.
- tests: download_sde via injected MockTransport, new lookups + None
  fallbacks, and SDE-vs-ESI fast-path/fallback for get_system/station.
- README: short offline-SDE setup note.
