Trim PROMPT.md.tmpl and review prompts — condense boilerplate

[federiconeri]

Problem

Several prompt templates have verbose sections that can be condensed:

PROMPT.md.tmpl (~81 lines)

• Design Quality Check (lines 45-54): 10 lines of checklist → 2 lines referencing the guide
• Security Review (lines 35-43): 9 lines → 2 lines referencing the guide
• Learning Capture (lines 63-70): 7 lines → 1 line
• Rules (lines 72-80): mostly duplicates Task section instructions

Review prompts (PROMPT_review_*.md.tmpl)

• 3 prompts with ~80% overlap (manual=121 lines, auto=155 lines, merge=194 lines)
• Each has Troubleshooting section (~6 lines) — Claude knows gh CLI
• Each has Learning Capture boilerplate (~7 lines)
• Each has verbose inline Claude review prompt (~20 lines)

Solution

PROMPT.md.tmpl

• Condense Design Quality Check to: "Before marking UI tasks complete, verify against @.ralph/guides/FRONTEND.md checklist."
• Condense Security Review to: "Review changes against @.ralph/guides/SECURITY.md. Run {{packageManager}} audit."
• Condense Learning Capture to: "If this iteration revealed useful patterns or mistakes, append to @.ralph/LEARNINGS.md."
• Remove redundant Rules that duplicate Task section

Review prompts

• Remove Troubleshooting sections from all 3
• Condense Learning Capture to 1 line in all 3
• Condense inline Claude review prompt

• src/templates/prompts/PROMPT_review_auto.md.tmpl

Estimated Reduction

~15 lines from PROMPT.md, ~20 lines per review prompt
