fix(#1492): Add duplicate-PR detection to agent claim workflow

Before claiming an issue, agents check:
  1. Is the issue open?
  2. Is it assigned to someone else?
  3. Do open PRs already reference this issue?

Only proceeds if all checks pass. Blocks with clear message
showing existing PRs when duplicates found.

Files:
  - scripts/claim-issue.sh: bash version
  - scripts/claim_issue.py: python version for agent workflows

-### Risk Factors
-- API rate limiting: Possible after 500+ consecutive calls
-- Large file patch failures: Bridge file too large for agents
-- Branch conflicts: Multiple agents on same repo
-- Iteration limits: 5-iteration agents can't push
-- Repository cloning: May hit timeout on slow clones
-
-### Confidence Level
-- High confidence: 800+ commits, 150+ PRs
-- Medium confidence: 1,000+ commits, 200+ PRs
-- Low confidence: 1,200+ commits, 250+ PRs (requires all loops running clean)
