chore(release): bump to v0.4.0 — conda-forge live PR automation

CondaForge.publish() runs the full feedstock-bump flow on --apply:
shallow clone, patch meta.yaml (version + sha256 + build.number),
commit on release-kit/bump-<version>, force-with-lease push,
open PR via API. Idempotent on existing open PR for same head.

181 tests pass; ruff + mypy strict clean. Build clean.

+## [0.4.0] — 2026-05-16
+
+### Added
+
+- **Conda-forge PR automation** (`be3f78d`, `462c9f2`): the
+  `conda-forge` platform plugin's `publish()` method now executes
+  the full feedstock-bump flow on `--apply`:
+  1. Shallow clone of the fork.
+  2. Patch `recipe/meta.yaml`: `{% set version %}` + `sha256:` +
+     `build.number` reset.
+  3. Create `release-kit/bump-<version>` branch, commit, force-with-
+     lease push to the fork.
+  4. Open the PR against the feedstock via the GitHub API.
+
+  Idempotent: an existing open PR for the same `<fork>:<branch>`
+  short-circuits with status `ok` and the existing PR URL.
+
+### Changed
+
+- `RE-AUDIT.md` updated with the final ship state (every Round
+  1/2/3/4 item resolved).
