Steve Yegge 42d2f71925 fix: Fix race condition in parallel issue creation (bd-89) ...

Use IMMEDIATE transactions with dedicated connections to fix race condition
where multiple processes creating issues concurrently caused "UNIQUE constraint
failed: issues.id" errors.

Key changes:
- Use BEGIN IMMEDIATE to acquire RESERVED lock early
- Use dedicated connection (sql.Conn) for transaction to ensure all operations
  happen on same connection
- Increase busy_timeout from 10s to 30s for better parallel write handling
- Use context.Background() for ROLLBACK to ensure cleanup even if ctx cancelled

Added regression test TestParallelIssueCreation that creates 20 issues in
parallel and verifies no ID collisions occur.

Fixes #6
