feat(release): CHANGELOG.md and release.yml — a tag becomes the release it claims (#32)

The PR-then-tag half of box#83's flow, rig's side. CHANGELOG.md starts
with an Unreleased section (feature PRs land their entry as part of the
PR — box's convention, now written into CONTRIBUTING alongside the
release ritual). On a tag push, release.yml asserts the bare tag equals
the tree's own VERSION — a mismatch fails loudly and creates nothing —
then creates the GitHub release with that version's changelog section as
the body, extracted by changelog_section in .github/scripts/release-lib.sh:
one function, sourced by the workflow and driven by test/release.sh
against fixtures and the shipped CHANGELOG.md itself. No assets — for a
pure-bash tree, the tag's source tarball IS the package.

# Changelog
History before 0.1.0 lives in git — rig grew its version surface (`VERSION`,
`rig --version`, the side-by-side `versions/<v>` install layout; #35/#36)
on the way to cutting its first release, and this file starts there.
## Unreleased
### Added
- **Tagged releases, and an installer that installs them** (#32) — the rig
half of the flow designed in heavy-duty/box#83, near-verbatim. A release
is a PR, then a tag: the `release: X.Y.Z` PR bumps `VERSION` and stamps
this file's Unreleased section with version + date; the merge commit is
tagged bare `X.Y.Z` (box's tag scheme — no `v` prefix). `release.yml`
turns the tag into the GitHub release — after asserting tag == `VERSION`
(mismatch fails loudly and creates nothing) — with that version's section
of this file as the body, extracted by the same `changelog_section` the
test harness drives. No assets: for a pure-bash tree, GitHub's source
tarball for the tag IS the package. `install.sh` now defaults to the
**latest release**: the tag is resolved by following the
`releases/latest` redirect and reading the `Location` header — no API, no
token — and the download is `archive/refs/tags/<tag>.tar.gz`. `RIG_REF`
picks the other two channels: a tag pins (`refs/tags` outranks a
same-named branch), a branch (`RIG_REF=main`) tracks the development
tree. Until 0.1.0 is cut the default channel has nothing to resolve and
dies saying exactly that, naming `RIG_REF=main` as the way to install
today — it never falls back to main silently, because "I installed the
latest release" must not quietly mean "I installed whatever main was that
second". Step 5 of #32 — pinning `BOX_REF` in the host-installs-box path
— stays open until box cuts its next tagged release.

8. **Feature PRs land their changelog entry as part of the PR** (box's
convention): add it under `CHANGELOG.md`'s `## Unreleased` heading —
that section becomes the release notes verbatim when a release is cut.
## Releasing
A release is a PR, then a tag (#32; box#83's design):
1. A small PR — `release: X.Y.Z` — bumps `VERSION` from `X.Y.Z-dev` and
stamps `CHANGELOG.md`'s Unreleased section as `## X.Y.Z — YYYY-MM-DD`.
CI green on it, same loop as any PR.
2. Merge, tag the merge commit bare `X.Y.Z` (no `v` prefix — box's tag
scheme), push the tag. `release.yml` asserts tag == `VERSION` (a
mismatch fails loudly and creates nothing) and creates the GitHub
release with that version's changelog section as the body. No assets —
the source tarball for the tag is the package `install.sh` downloads.
3. A follow-up (or the next feature PR) bumps main's `VERSION` to
`X.Y.(Z+1)-dev`, so a dev install never impersonates the release in the
`versions/<v>` layout.
