/**
 * Exit-status decoding for `S2C_EXITED` frames.
 *
 * The server encodes a process exit status as a signed 32-bit integer in the
 * `S2C_EXITED` frame (`crates/remote/src/lib.rs`, wire layout
 * `[0x08][pty_id:2][exit_status:4]`, little-endian):
 *
 *  - `>= 0` — normal exit; the value is the `WEXITSTATUS` exit code.
 *  - `< 0`  — terminated by a signal; the value is the negated signal number.
 *  - {@link EXIT_STATUS_UNKNOWN} — the status has not been collected yet.
 *
 * These helpers mirror the canonical Rust implementation in
 * `crates/cli/src/agent.rs` (`exit_code_from_status` / `format_exit_status`)
 * so JS consumers don't have to re-derive the `128 + signal` convention.
