Creates migration to detect orphaned child issues and logs them for user
action. Orphaned children are issues with hierarchical IDs (e.g., "parent.child")
where the parent issue no longer exists in the database.
The migration:
- Queries for issues with IDs like '%.%' where parent doesn't exist
- Logs detected orphans with suggested actions (delete, convert, or restore)
- Does NOT automatically delete or convert orphans
- Is idempotent and safe to run multiple times
Test coverage:
- Detects orphaned child issues correctly
- Handles clean databases with no orphans
- Verifies idempotency

Introduces a materialized cache table to store blocked issue IDs,
replacing the expensive recursive CTE computation that was causing
~752ms query times on 10K databases (bd-5qim).
The cache is maintained via invalidation on dependency and status
changes, reducing GetReadyWork from O(n²) recursive traversal to
O(1) cache lookup.
Technical details:
- New blocked_issues_cache table with single issue_id column
- ON DELETE CASCADE ensures automatic cleanup
- Migration populates cache using existing recursive CTE logic
- rebuildBlockedCache() fully rebuilds cache on invalidation
- execer interface allows both *sql.DB and *sql.Tx usage

- Force single connection for all in-memory databases (including file::memory:)
- Close rows before executing statements in external_ref migration
- Prevents connection pool deadlock with MaxOpenConns(1)
- Fixes test failures in syncbranch_test.go
The schema initialization was trying to create an index on the external_ref
column before the migration that adds the column runs. This caused 'no such
column: external_ref' errors when opening very old databases (pre-0.17.5).
Solution: Move the index creation into the migration that adds the column.
Fixes#284
