Removed the workspace-level clippy lint config that enabled all, pedantic, nursery,
and cargo lint groups. Removed all #[allow(clippy::...)] annotations that were only
needed to suppress those extra lints, and fixed the few default clippy warnings that
were uncovered.

Thread CancellationToken into tool executors and exec_command so that
running processes are killed (SIGTERM -> 2s -> SIGKILL) when abort fires,
rather than only checking the flag between LLM calls. Key changes:
- ToolExecutor type gains CancellationToken parameter
- ExecutionEnvironment::exec_command gains cancel_token param
- LocalExecutionEnvironment uses tokio::select! (completion vs timeout
vs cancellation) with extracted sigterm_then_kill helper
- DockerExecutionEnvironment uses same select! pattern
- Session replaces Arc<AtomicBool> with CancellationToken, passes
child_token() per tool call
- Shell tool forwards cancel token to exec_command
- CLI SIGINT handler calls cancel_token.cancel()

Implements ExecutionEnvironment trait backed by Docker containers via
bollard. Host working directory is bind-mounted; all file ops, commands,
grep, and glob execute inside the container via docker exec. Extracts
shared format_lines_numbered() helper from LocalExecutionEnvironment.
