portable_pty 0.0.3+1

Cross-platform pseudo-terminal (PTY) for Dart. Spawns shell subprocesses on Linux, macOS, and Windows via a Rust native library. On web, connects through WebSocket or WebTransport to a remote PTY server.

0.0.3

• Fixed child process exit codes being incorrectly reported as 0 when running under the Dart test runner. The Dart VM's internal waitpid(-1, 0) thread was reaping PTY children before tryWait() could capture their exit status.
• SIGCHLD handler now extracts exit status from the siginfo_t structure (populated by the kernel at signal delivery time), unaffected by concurrent reaping from other threads.
• Added lock-free PID registry (64 slots) with signal chaining and automatic re-installation if overwritten.
• SIGCHLD is blocked during spawn to prevent a race between child exit and PID registration.
• Cached exit code on the PTY handle so repeated tryWait/wait calls return consistent results.
• Pre-emptive waitpid and kill(pid, 0) fallback paths for robustness when the SIGCHLD handler misses a coalesced signal.

0.0.2

• Added dart run portable_pty:setup command to download prebuilt native libraries for downstream consumers.
• Build hook now finds prebuilt libraries at the consuming project's .prebuilt/<platform>/ directory, eliminating the need to modify the pub cache.
• Build hook search order: env var, monorepo .prebuilt/, project .prebuilt/.
