* feat(kiro_cli): add full TUI mode support with --legacy-ui fallback (awslabs#159)

Remove hardcoded --legacy-ui from launch command and add TUI-native
status detection and message extraction. The provider now:

- Launches in TUI mode by default, falls back to --legacy-ui on timeout
- Detects COMPLETED via ▸ Credits: marker + idle prompt (TUI path)
- Extracts messages using separator (────) boundaries when no green arrows
- Retains full backward compatibility with legacy UI patterns

Also adds "aren't available" to e2e REFUSAL_KEYWORDS for Claude Code test fix.

* fix(kiro_cli): address PR awslabs#163 review comments

- Raise separator minimum from 4 to 20 chars to avoid matching short
  markdown separators in agent output (jwalaQ comment #4)
- Remove redundant ANSI cleanup in _extract_tui_message — input is
  already ANSI-stripped by caller (jwalaQ comment #5)
- Improve timeout error message wording (jwalaQ comment #3)

* feat(kiro_cli): add TUI processing and permission detection patterns

- Add "Kiro is working" ghost text as positive PROCESSING signal,
  checked before idle prompt absence (jwalaQ comment #1)
- Add TUI permission pattern "Yes No Always Allow" alongside legacy
  [y/n/t] format, requires all three options to avoid false positives
  on bare "Yes"/"No" in agent output (jwalaQ comment #2)

* fix(kiro_cli): update TUI idle pattern to match real kiro-cli v1.29+ output

Verified against real kiro-cli v1.29.1 TUI output via tmux capture-pane:
- Idle prompt is "Ask a question or describe a task" (capital A, no comma)
- Pattern now accepts both old (lowercase, comma) and new formats
- Updated fixtures to use real TUI output format
- Updated inline test strings to match v1.29+ output

* fix(kiro_cli): use forward-search for TUI separator to handle agent output separators (awslabs#159)

Changed _extract_tui_message() to find the first separator after the
previous turn's Credits line instead of the last separator before the
current Credits. This prevents false matches when agent output contains
box-drawing separator characters. Also updated docs for launch command.
