fix: address review feedback — enforce maxRetries, wire abort signal, use cross-platform shell

1. Enforce maxRetries: track auto-fix attempts per query chain in toolHooks.ts
   and stop feeding errors back after the configured limit is reached.

2. Wire abort signal to subprocess: subscribe to AbortController signal in
   runCommand() and kill the process tree on abort. Uses detached process
   groups on Unix to ensure child processes are also terminated.

3. Replace hardcoded bash with shell:true: use Node's cross-platform shell
   resolution instead of spawn('bash', ['-c', ...]) so auto-fix commands
   work on Windows and non-bash environments.
