ci: cover models.json in the alignment guardrail; fix release.yml's no-CHANGELOG path

Two CI-layer fixes found during the v3.25.0 review. Same layer, both small, so
they land together (Iron Rule 11).

#198 — alignment.yml did not run on a models.json-only PR.
The `paths:` filter listed server.mjs / setup.mjs / scripts / lib / ocp /
ocp-connect, but not models.json. That made CLAUDE.md hard-requirement #2 ("CI
blacklist pass") vacuous for exactly the PRs that change model routing:
confirmed on #192, where only gitleaks and test-features ran.

models.json is not inert data. It drives MODEL_MAP and VALID_MODELS, the
default request model, and — since ADR 0009 — the global MAX_PROMPT_CHARS
truncation budget. A models.json-only PR can therefore change server.mjs's
runtime behavior with the guardrail never running. models.schema.json is
included for the same reason one level up: loosening the schema is what would
let a malformed models.json through.

Adding paths only widens coverage; the blacklist grep still scans server.mjs,
so this costs nothing and closes the gap. Per CLAUDE.md this is a PR amendment
to alignment.yml, which is the sanctioned way to change it (removing entries
would need an ALIGNMENT.md amendment; nothing is removed here).

#202 — release.yml's no-CHANGELOG fallback would have failed the release job.
The branch wrote an output named `notes` and exited WITHOUT creating
/tmp/release-notes.md, while the create step hard-codes
`--notes-file /tmp/release-notes.md`. So the one path that exists to "degrade
to minimal notes" instead produced a failed release.

Verified both directions by extracting the step's actual script from the YAML
and running it, rather than reading it:

  PRE-FIX,  no CHANGELOG -> exit 0, GITHUB_OUTPUT="notes=Release v3.25.0",
                            /tmp/release-notes.md MISSING
                            -> gh release create --notes-file WOULD FAIL
  POST-FIX, no CHANGELOG -> exit 0, notes_file set, file present ("Release v3.25.0")
  POST-FIX, with CHANGELOG -> file present, first line "## v3.25.0 — 2026-07-27"

Fixed by writing the file in that branch, and by removing the hard-coded-path
coupling entirely: both branches now set `notes_file` and the create step
consumes `steps.notes.outputs.notes_file`. That output existed already and was
never read — the two only agreed by accident.

Also added `set -euo pipefail` (the step previously ran unset-tolerant) and an
echo of the resolved notes before creating the release, so a wrong-looking body
is visible in the job log instead of only on the published release.

NOT changed: the empty-extraction guard. My issue text suggested adding one,
but `if [ ! -s "$NOTES" ]` was already there and already handles a heading
mismatch. Correcting that claim on #202 rather than taking credit for it.

Both workflows re-validated as YAML.
