v5.8.23: Add Go unit tests for context cancellation verification

- Add context cancellation check during COPY data parsing loop
  (prevents hangs when parsing large tables with millions of rows)
- Add 5-second timeout for stderr reader in globals restore
  (prevents indefinite hang if psql process doesn't terminate cleanly)
- Reduce database drop timeout from 5 minutes to 60 seconds
  (improves TUI responsiveness during cluster cleanup)

+## [5.8.23] - 2026-02-05
+
+### Added
+- **Cancellation Tests**: Added Go unit tests for context cancellation verification
+  - `TestParseStatementsContextCancellation` - verifies statement parsing can be cancelled
+  - `TestParseStatementsWithCopyDataCancellation` - verifies COPY data parsing can be cancelled
+  - Tests confirm cancellation responds within 10ms on large (1M+ line) files
