feat(worker): add Claude CLI preflight on startup

Browse Source 
Worker now runs `claude --version` before listening; on non-zero exit
it logs critical and exits with code 1. Skippable via env var
CLAUDEDO_SKIP_CLI_PREFLIGHT=1 for environments without the CLI (tests,
dev). Closes verification step 2 / open.md item 3.1.
