📝 Walkthrough

Walkthrough

Added Android-specific POSIX scheduling constants (SCHED_DEADLINE and SCHED_NORMAL) to RustPython's posix module via libc imports. Updated libc version dependency from 0.2.177 to 0.2.180 and adjusted Python documentation references from version 3.13 to 3.14.

Changes

Cohort / File(s)	Summary
Android POSIX Scheduling Constants `crates/vm/src/stdlib/posix.rs`	Added Android-targeted `#[pyattr]` exports for `SCHED_DEADLINE` and `SCHED_NORMAL` from libc, making these scheduling constants available as Python attributes on Android targets.
Libc Dependency and Documentation `scripts/libc_posix.py`	Updated libc version constant from 0.2.177 to 0.2.180 and updated Python os module documentation URL reference from version 3.13 to 3.14.
