Module tools 

Deterministic tools capability.

Ports the Swift CoreToolExecutor surface: search (ripgrep via grep-searcher + ignore), file I/O, listing, file outline, git inspection, and process lifecycle (run_command, run_test, run_build_command, inspect_test_results, manage_packages).

Implementation status:

Method	Status
search	implemented
read_file	implemented
write_file	implemented
delete_file	implemented
list_directory	implemented
get_file_outline	implemented (regex extractor)
git	implemented (system git CLI)
run_command	implemented
run_test	implemented
run_build_command	implemented
inspect_test_results	implemented
manage_packages	implemented

Per-session opt-in

All deterministic tools are gated by a per-thread feature flag. Pipelines must call hostlib_enable("tools:deterministic") (registered by ToolsCapability::register_builtins) before any of the tool methods will execute. Until then, calls return HostlibError::Backend with an explanatory message. The per-session opt-in model keeps the deterministic-tool surface sandbox-friendly.
