fix: Update ready_issues VIEW to use hierarchical blocking

The ready_issues VIEW was using old logic that didn't propagate blocking
through parent-child hierarchies. This caused inconsistency with the
GetReadyWork() function for users querying via sqlite3 CLI.

Changes:
- Updated VIEW to use same recursive CTE as GetReadyWork()
- Added test to verify VIEW and function produce identical results
- No migration needed (CREATE VIEW IF NOT EXISTS handles recreation)

The VIEW is documented in WORKFLOW.md for direct SQL queries and is now
consistent with the function-based API.
