v0.5.0

Highlights since v0.4.0:

Features:

• dvx diff -p/--pull: auto-fetch missing cache blobs from the remote for either revision (with --remote to pick a non-default remote).
• dvx diff resolves meta.git_tracked: true files via git show <ref>:<path>, bypassing the cache/remote entirely — diffs across history work even when the blob was never pushed, and with no remote configured.

Bug fixes:

• dvx run --push each: push every co-output's blob, not just the primary's (previously a 2-output stage shipped only 1 blob, silently breaking next-day dvx pull).
• dvx pull -R <ref> and pull_hashes: fix DVC API drift (repo.odb.local → repo.cache.local, dead tqdm callback). dvx pull -R had been broken since the upstream DVC rename.
• dvx pull --glob: thread --glob through the targeted-pull path.
• ArtifactStatusDB: fix cold-start database is locked race.
• get_dep_hashes: fall back to the recorded md5 when the dep file is absent.
• dvx run: stop walking upstream past fresh artifacts.

Internal:

• Tests sweep: parse CLI output into structured form, assert via exact equality (no in result.output substring checks).
• --push each co-output semantics documented in MULTI_OUTPUT.md.
