v0.4.4

0.4.4

Improved

• Scoped cached test-status baselines to the current working directory instead of one global last-run file, so sift rerun and sift escalate no longer pick up another project's state.
• Clarified the test-status cache lifecycle in the CLI reference, including where the baseline lives, when it is written, and how to reset it.
• Reworked the test pyramid so the default suite stays source-backed and fast, with a much thinner smoke layer and separate built-artifact E2E coverage.

Added

• Added dedicated integration coverage for exec, rerun, and escalate orchestration without relying on a full outer CLI subprocess for every behavior branch.
• Added a separate E2E lane for dist, packaging, and docs acceptance flows, plus an E2E-only Vitest global setup.
• Added consistent test-layer suffixes across the remaining legacy *.test.ts files (*.unit.test.ts, *.integration.test.ts, *.smoke.test.ts, *.e2e.test.ts).

Changed

• Updated CI and release workflows to use the split test commands explicitly: coverage, smoke, and E2E now run as distinct lanes.
• Updated contributor-facing docs so the README points to CONTRIBUTING.md, and CONTRIBUTING.md explains the new unit/integration/smoke/E2E boundaries.
• Hardened fake-provider test stability and one-shot provider requests so subprocess-heavy test runs shut down more reliably.
• Bumped package version to 0.4.4.
