docs(contributing): trim to goose-scale minimal intake surface (#2780)

Replace the 5-file, ~180-line template surface with a 4-file, ~54-line
goose-modeled set.

## What changed

**`.github/PULL_REQUEST_TEMPLATE.md`** — rewritten to 8 lines: Summary,
Related issue (with inline duplicate-check prompt), Testing. Checklist
and AI-disclosure section removed.

**`.github/ISSUE_TEMPLATE/bug-report.yml` → `bug-report.md`** — replaced
YAML form with plain-markdown template (goose-style frontmatter).
Fields: describe the bug, repro steps, expected behavior, version + OS,
logs/context. Version guidance retained: Settings sidebar footer,
"unknown" accepted.

**`.github/ISSUE_TEMPLATE/feature-request.yml` → `feature-request.md`**
— replaced YAML form with plain-markdown template. Fields: motivation,
proposed solution, alternatives, additional context. Duplicate-check
line at the bottom (goose-style).

**`.github/ISSUE_TEMPLATE/question.yml`** — deleted. `config.yml`
updated to `blank_issues_enabled: true` so questions have somewhere to
go.

**`CONTRIBUTING.md`** — "Before You Open a PR" compressed to four prose
sentences: duplicate search, issue-first recommendation, AI ownership
(absorbs the dropped PR-template field), review cadence. Intro link
updated from the removed question form to plain `/issues/new`.
