Add Auto/Review mode toggle and non-interactive runner

- GUI: Auto/Review toggle on TaskDetail and ProjectView
  persisted per-project in localStorage
- Runner: noninteractive param (stdin=DEVNULL, 300s timeout)
  activated by KIN_NONINTERACTIVE=1 env or param
- CLI: --allow-write flag for kin run command
- API: POST /run accepts {allow_write: bool}, sets
  KIN_NONINTERACTIVE=1 and stdin=DEVNULL for subprocess
- Fixes pipeline hanging on interactive claude input (VDOL-002)
