feat(process): implement asynchronous process execution module#19
Merged
Conversation
Introduces the `ns_process` module to allow non-blocking, background process execution. This enables the C main thread to safely orchestrate concurrent tasks (like downloading data and running media players) without freezing. Key additions: - Implemented `ns_process_spawn` to launch background processes via `sh -c`. - Implemented `ns_process_is_running` for non-blocking status polling. - Implemented `ns_process_kill` to forcefully terminate active child processes. - Implemented `ns_process_free` to safely clean up heap handles and prevent zombie processes. - Enforced strict FFI safety by marking raw pointer dereferences as `unsafe` and adhering to Clippy standards. Fixes & Examples: - fix(cmd): Updated `ns_cmd` error mappings to strictly use `NsError::Any` to comply with the updated `ns_error` enum. - test: Added `16_process.c` demonstrating background execution and early termination. - test: Added `17_concurrent.c` demonstrating non-blocking multi-process orchestration (curl + mpv).
