Description

Add tests for rendering, navigation, and task moves; ensure no crashes and smooth behavior for large data sets.

Acceptance Criteria

• [x] #1 Unit/integration tests cover rendering and navigation
• [x] #2 Tests cover move flows and dependency updates
• [x] #3 No crash or unhandled errors during typical flows
• [x] #4 Tests cover Unsequenced bucket rendering in TUI and --plain output
• [x] #5 Tests verify join semantics: moving into a sequence sets moved deps to previous sequence only; other tasks unchanged
• [x] #6 Tests block moving to Unsequenced when task has deps/dependees; shows clear message
• [x] #7 Tests ensure moving from Unsequenced to Sequence 1 anchors with ordinal when deps remain empty

Implementation Plan

1. Add core helper to check Unsequenced eligibility; reuse in TUI\n2. Add tests: eligibility, computeSequences coverage, and join/insert moves already present\n3. Add a headless TUI content test for Unsequenced ordering\n4. Run lint/types/tests; fix issues\n5. Mark task Done with notes

Implementation Notes

Added tests for Unsequenced eligibility and leveraged existing coverage for sequences plain output, headless fallback, join and insert-between moves, and reorder. Introduced canMoveToUnsequenced in core and integrated in TUI to block invalid Unsequenced moves. Verified no crashes, types, and linting; ran full test suite (no env overrides).
