Walkthrough

_TextIOBase in the VM's _io module gains explicit _unsupported stub implementations for read, write, truncate, readline, and detach, plus a newlines property getter that returns None, mirroring the existing encoding getter pattern.

Changes

_TextIOBase stubs and newlines getter

Layer / File(s)	Summary
_TextIOBase _unsupported stubs and newlines property `crates/vm/src/stdlib/_io.rs`	Adds `read`, `write`, `truncate`, `readline`, and `detach` as `_unsupported` method stubs, and a `newlines` getter returning `None`, to the `_TextIOBase` Python class.

Poem

🐇 Hop hop, the base class grows,
With stubs for reads and writes in rows,
newlines returns a gentle None,
detach and truncate—nicely done!
The rabbit checks each method off,
No unsupported path too rough. 🌿
