v0.4.0

Highlights since v0.3.0:

Features:

• dvx run --push each|end now also pushes cache blobs to the remote (not just git push), preventing "cache files do not exist" errors in downstream runs. Opt out with -P/--no-cache-push.
• dvx run caches output blobs locally so historical versions stay retrievable.
• dvx status groups output by status (Stale → Missing → Transitive → Error → Fresh) with colored headers and counts. Filter with -s/--status (include) and -x/--omit (exclude), both prefix-matched (s → stale, m → missing, etc.). Flatten with -G.
• Version-aware dvx gc with --keep N and --older-than retention policies.
• .dvx/config.yml for run config with per-stage commit/push overrides.
• dvx.stage IPC library (stage.commit(), stage.summary(), stage.push()).
• Side-effect stages (no outs, deps-only freshness) for deploys, syncs, posts.
• Fetch schedules (daily/hourly/weekly/cron) for periodic data re-fetch.
• Directory git_deps via git tree SHAs.
• dvx import-url --git — git-tracked imports with URL provenance and -A User-Agent.
• Transitive staleness in dvx status (⚠ for indirectly stale stages).
• Colored status output: ✗ red, ? magenta, ⚠ yellow, ✓ green.
• Recursive .dvc discovery in dvx run (no targets = find all .dvc files).
• /-prefixed dep shorthand for out-of-dvc-dir deps (vs ../../ chains).

Bug fixes:

• Fix stale dep hashes written to .dvc after execution.
• Fix targeted dvx pull for .dvc files (bypass dvc.yaml).
• Fix side-effect stage path resolution in subdirectories.
• Fix dep freshness check for raw files without .dvc.
• Fix per-stage push config not gated on global push being enabled.
• Fix Z suffix in ISO 8601 parsing for Python 3.10.
• is_fetch_due: raise clearly when croniter is missing.

Internal:

• Vendor Meta.from_info mtime patch; depend on upstream dvc-data from PyPI.

Removed:

• after: stage ordering (redundant with git_deps on upstream .dvc files; never released to PyPI).
