IMP-5: Replace strings.Contains(arg, ":") heuristic with an allowlist of recognized attribute keys (ValidAttributeKeys). Colons in task descriptions (URLs, "Meeting: topic") are no longer misinterpreted as modifiers. Canonical key sets live in engine/keys.go and are shared across parseAddArgs, ParseFilter, and ParseModifier. ParseModifier now errors on unknown keys. IMP-4: delete command now loads the working set and resolves display IDs via GetTaskByDisplayID, matching the pattern used by done/modify. IMP-6: All action commands (done, delete, modify, start, stop) now return an error on no-match (stderr, exit 1). Previously done/delete printed to stdout and exited 0; start/stop had no check at all. Also adds requirements and design docs for the CLI UX improvements. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
