Refactoring

• Unified text input system — replaced three separate text input implementations (FormWizard text-step, InputPanel, command-bar) with a shared architecture inspired by Claude Code:
  • text-cursor.ts — immutable Cursor class with NFC normalization and Intl.Segmenter-based grapheme navigation (CJK, emoji, Cyrillic, combining marks)
  • hooks/useTextInput.ts — keyboard logic hook with undo stack (Ctrl+Z / Cmd+Z), kill ring (Ctrl+K/U/W/Y), word navigation (Option+Left/Right), and all terminal editing shortcuts
  • components/TextInput.tsx — display component with sliding viewport that keeps cursor visible on text overflow

Bug Fixes

• Cursor jumping on keyboard language switch — NFC normalization in Cursor constructor prevents position drift when IME sends NFD-encoded characters during layout switching
• Text overflow at screen edge — single-line text inputs now use a sliding viewport instead of truncating from the end, keeping the cursor always visible
• Undo stack over-drain — debounced undo snapshots captured current state, causing Ctrl+Z to pop identical text with no visible effect; fixed by skipping one matching snapshot before applying undo
• React anti-pattern in textarea — setTaCursorCol was called inside a setTaLines updater function; moved out to prevent potential double-fire in concurrent mode
• Timer leak on unmount — undo debounce timer is now cleared via useEffect cleanup when the component unmounts mid-debounce

Performance

• Zero-cost cursor navigation — arrow keys, Home/End, word navigation reuse existing grapheme segments via Cursor._withPos() factory instead of re-running Intl.Segmenter on unchanged text
• Single-pass insert — Cursor.insert() uses graphemeSegments() once instead of graphemeLength() + constructor re-segmentation
• Render-path optimization — TextInput reads cursor.beforeSegs / cursor.afterSegs directly, avoiding join + re-segmentation on every render

New Features

• Editing shortcuts — Ctrl+A/E (start/end), Ctrl+K/U/W (kill operations), Ctrl+Y (yank), Ctrl+Z / Cmd+Z (undo), Cmd+Backspace (kill to start), Ctrl+B/F (left/right), Ctrl+D (delete forward), Ctrl+H (backspace), Home/End keys

Tests

• 96 new tests (1829 → 1923):
  • text-cursor.test.ts (61 tests) — grapheme segmentation, NFC normalization, CJK/emoji/Cyrillic handling, cursor navigation, editing, kill operations, display width
  • text-input.test.tsx (33 tests) — E2E via ink-testing-library: FormWizard text-step input/submit, cursor navigation, backspace, all Ctrl shortcuts, Cyrillic/emoji/CJK input, undo, step transitions, validation

Bug Fixes

• Parallel runs race condition (#8) — when multiple agents completed in parallel via orch serve, successful runs were falsely marked as failed. Root cause: reconcile detected dead PIDs before handleRunSuccess acquired the mutex, treating clean exits as crashes. Fix: activeCollectors guard prevents reconcile from interfering with tasks that have an active event collector. Also fixes orphaned runs stuck in status: running when the running entry was already cleaned up
• Assignee name resolution (#7) — tasks assigned by agent name (e.g. --assignee "Sam Altman") instead of agent ID were silently accepted but never dispatched. TaskService.resolveAssignee() now normalizes agent names to IDs at creation and assignment time, with clear error messages for unknown agents. findBestAgent() also matches by name as a fallback for legacy data

Tests

• 15 new tests: activeCollectors guard (reconcile skip, crash detection, cleanup, orphaned run finalization), assignee name→ID resolution (create, assign, unknown name/ID, backward compatibility, findBestAgent name fallback)

Bug Fixes

• Goal completion deadlock — agents could not mark their own goal as achieved because the agent's running [auto] task blocked the pending-tasks guard. Autonomous tasks are now excluded from the check since they are the mechanism for achieving the goal, not a blocker
• paused → achieved transition — goals in paused state can now be directly marked as achieved without requiring a resume first. State machine updated: paused → active | achieved | abandoned
• TUI force-complete — pressing C on a goal in TUI now uses force: true to cancel cancellable pending tasks, with an informative status message. Previously it would silently fail if any non-terminal tasks existed

Tests

• 4 new tests: autonomous task exclusion from pending check, non-auto task still blocks, paused → achieved with side effects, paused → achieved with force + pending tasks
