chore: align pr templates

[ovitrif]

Closes #1261

This PR gives the PR template one shape shared with bitkit-ios: scope stated in the description, one line of design guidance, and QA Notes with its subsections.

Description

• Adds an #### Out of Scope subsection at the end of ### Description so reviewers read the author's non-goals instead of guessing them.
• Requires the subsection for feat, fix, and refactor PRs; version bumps, changelog, and release PRs skip it, and other chores include it at the author's discretion.
• Asks for one bullet per change under ### Description, what changed and why, so the intent of each change is on record.
• Shortens the ### Design guidance to one line; the full rules stay in the /pr command.
• Ships #### Manual Tests and #### Automated Checks under ### QA Notes, the structure the /pr command already generates.
• Teaches the /pr command the scope rules so agent-authored PRs follow them.

Out of Scope

• .agents/commands/release.md: version-bump PRs keep their fixed body; the scope subsection is for behaviour changes.
• Back-filling the sections on PRs that are already open.
• Enforcing the sections in CI: a later change once the team has used them for a while.

Design

N/A — no UI changes.
