Reduce duplicate issue creation between DeepReport and Code Quality task-mining workflows

[Copilot]

DeepReport and Code Quality agents were generating overlapping issues for the same underlying fixes, creating duplicate backlog entries and split ownership. This change adds explicit, lightweight dedup controls so issue-filing workflows converge on canonical open issues instead of re-filing similar work.

• Workflow-level dedup guardrails

  • Added deduplicate-by-title to safe-outputs.create-issue in:
    • .github/workflows/deep-report.md
    • .github/workflows/discussion-task-miner.md
  • This enables built-in near-title matching before issue creation.

• Prompt-level topic similarity policy

  • Updated both workflow prompts to require a pre-create dedup gate:
    • search open issues by title/topic/component terms,
    • treat same component + same fix intent as duplicate,
    • skip creation and reference canonical issue when overlap is found.

• Compiled workflow outputs updated

  • Regenerated:
    • .github/workflows/deep-report.lock.yml
    • .github/workflows/discussion-task-miner.lock.yml

safe-outputs:
  create-issue:
    title-prefix: "[deep-report] "
    deduplicate-by-title: 28

• Fixes [deep-report] Consolidate duplicate goroutine/HTTP-timeout fix issues filed by DeepReport and Code Quality agents #47811
