[refactor] idd-list Step 5: needs-fix × PR state matrix 應展開,不該摺疊成單行 (verify follow-up from #13)

[kiki830621]

Problem

From verification of #13 (DA-4, MEDIUM — devil's advocate):
Step 5 phase × PR state matrix 把所有 needs-fix 摺疊成「(任何) → /idd-diagnose #N」,遺漏 critical case:re-verify after push fix + CONFLICTING 場景。

Type

refactor / spec completeness

Why P3

• needs-fix 通常觸發場景是「verify FAIL → user push fix → 應 re-verify」,re-verify 必然要對既有 PR 操作(若走 PR path)
• 實際 user flow:needs-fix + PR=CONFLICTING → 應 prompt gh pr checkout N → resolve → /idd-diagnose #N,而非單純 /idd-diagnose #N
• spec 自己埋了 backward gap — needs-fix 處理是 v2.50 phase-only 規則延續,沒享受 v2.51 PR awareness 改造

Recommendation

Step 5 matrix 展開 needs-fix 為 4 row(no PR / draft / ready+MERGEABLE / CONFLICTING),各對應 actionable next。

Closing Summary (retroactive — already shipped in v2.51.0)

Problem

(See issue body)

Resolution

已在 v2.51.0 (commits 1c60c1c + 2564d6f) shipped。Issue body 一直沒 close,本次 retroactive close。

具體實作位置:needs-fix × PR state matrix 已展開為 3 rows (no PR / draft|ready,MERGEABLE / ready,CONFLICTING),line 265-267。

該 finding 在 v2.51.0 設計 spec 階段就被內化吸收(verify-fix 2564d6f 處理 7 blocking + 6 in-scope findings,本 issue 是 in-scope 範疇之一)。

Verification

直接讀 spec:plugins/issue-driven-dev/skills/idd-list/SKILL.md 確認對應 spec language 已存在 + 與本 issue acceptance criteria 對齊。

Changes

• 1c60c1c feat(idd-list): show open PRs ref'ing each issue + cluster detection (idd-list 應該顯示引用 issue 的 open PR 資訊 #13)
• 2564d6f fix(idd-list): 7 blocking + 6 in-scope verify findings (idd-list 應該顯示引用 issue 的 open PR 資訊 #13)
