fix(ci): make PR-template inline-description contract explicit (#10558)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Contributors use the PR template to describe changes before review
> - The linked-issue gate reads literal template labels, not freeform
prose
> - The template did not state that rule, so a good prose summary could
fail on first submission
> - The gate also skipped two issue template paths that the PR template
already points to
> - This pull request makes the template and the gate match the same
contract
> - The benefit is that a good-faith author can pass the check on the
first try

## Linked Issues or Issue Description

No public issue exists.

Related public PR: #7762.

The problem is a mismatch between the PR template and the linked-issue
gate.
The template gave a bare placeholder and did not explain the
literal-label rule.
The gate also missed the enhancement and docs issue templates.

## What Changed

- Replaced the bare PR-template placeholder with labeled inline
skeletons for bug, feature, and adapter paths.
- Added one sentence that says the gate reads literal labels on separate
lines.
- Added the enhancement and docs issue template field sets to the
linked-issue gate.
- Added and updated tests for prose-only bodies, template skeleton
bodies, and extra issue template coverage.

## Verification

- `node --test .github/scripts/tests/check-pr-linked-issue.test.mjs`
- The branch contains one commit:
`561f1ed3a1434ed4562306f74d40968163ef1444`

## Risks

Low risk.
The three-field minimum stays in place.
The main change is clearer author guidance in the PR template.

## Model Used

OpenAI Codex, GPT-5, tool use.

(B) No issue exists — describe the underlying problem here, following the

An automated check reads the literal bold labels AND the content under
each label. Keep at least three of these labels, each alone on its own
line, and write real content under each. A label with only the bare "-"
placeholder does not count, and the check fails.
