Summary

• Phase 9 now generates a numbered structure with the duplicate-check on step 1 (closes Template should generate numbered Phase 9 structure with duplicate-check on line 1 #9)
• Step 4 substitution-table preamble notes it covers {{#if FLAG}} conditionals too (closes Step 4 substitution table should note it covers {{#if FLAG}} conditionals too #10)
• Phase 3 gains universal match sibling structure + rename siblings together rules — promoted from kingdom-first-era-dev-loop#1 / Add README and CLAUDE.md documentation #2 because they generalize to any repo, not just KFE docs
• Edge cases gain a flaky-test entry — promoted from example-l-dev-loop#12 because every tests-running loop will hit this

This is the first PR in a series bringing all dev-loop skills into line with the conventions just codified in example-skills-catalog/CONVENTIONS.md. Subsequent PRs against example-h-dev-loop, example-k-dev-loop, kingdom-first-era-dev-loop, and example-a-dev-loop will retrofit the same Phase 9 structure into existing generated skills.

Test plan

• Visual review of create-dev-loop.md Phase 3, Phase 9, Step 4, and Edge cases sections
• Confirm the new Phase 3 universal rules read clearly without contradicting {{CODE_PATTERNS}} substitution
• Confirm the new flaky-test entry doesn't conflict with the existing "Tests fail during implementation" entry (they're complementary — that one is for real failures, this one is for re-run-resolvable flakes)

Closes #9
Closes #10

Self-review: found one bug, fixed in 0ff1aea — the new gh issue create block in Phase 9 used \ (double backslash) for line continuations instead of the single \ used everywhere else in the file. Would have rendered as literal \ in the generated skill and broken shell parsing. No other issues found on a second pass over the diff.
