docs(pr-quality): add collapsed sections formatting, fix reviewer identity

[Copilot]

The github-actions bot reviewer produces long, unscannable review comments on mobile. Add <details><summary> formatting guidance so reviews use collapsible sections grouped by category.

Changes

• Collapsed sections (step 7): Instruct the reviewer to wrap multi-topic feedback in <details> blocks with emoji-prefixed summaries (♿ accessibility, ⚡ performance, 🐛 bugs, 🧹 style, 🔒 security)
• CI Summary: Wrap the status table example in a collapsible <details> block — it's reference data, not the main review content
• Remove incorrect identity claim: Deleted paragraph that described the reviewer as "first automated reviewer" under the "Copilot identity" — this workflow runs as github-actions bot

Example of the target review format:

**2 issues found, 1 blocking.**

<details>
<summary>♿ Accessibility concerns (2 items)</summary>
