Introduce prepare-release for the deterministic parts of preparing a
release. Update AGENTS.md to use that, rather than using an LLM for
deterministic steps.
finalize-release now pushes the release commit and tag after signing, and
prepares a release announcement mail.

Document the release workflow in AGENTS.md, splitting it into
agent-preparable draft steps and human-only finalization. Add
scripts/finalize-release which amends the version bump commit with
Signed-off-by, creates a signed tag, and optionally invokes kup-dtc
for upload. Remove the now-redundant dist and kup targets from the
Makefile.
