chore: release channels v0.7.3 (#6375)

## Release channels v0.7.3

**Scope:** `channels` | **Bump:** `patch`

---

### How this release process works

1. **This PR was created automatically** by the "release / create-pr"
workflow.
   It bumped the `channels` packages to `0.7.3`
   and generated AI-enhanced release notes.

2. **CI runs on this PR** — the full test suite (unit tests, lint, type
checks, build)
   must pass before merging. This is the review gate.

3. **Review the release notes** in `release-notes.md` in this PR.
If a Notion draft was created, you can edit the release notes there
before merging.

4. **When this PR is merged**, the `release / publish` workflow
automatically:
   - Builds all packages
   - Publishes the `channels` packages to npm at version `0.7.3`
   - Creates git tag `channels/v0.7.3`
   - Creates a GitHub Release with the final release notes

### Before merging

- [ ] CI is green (tests, lint, types, build)
- [ ] Version bumps look correct
- [ ] Release notes are accurate (edit in Notion if a draft was created)

> **Do not merge until CI is fully green.** The full test suite runs
automatically on this PR.
