fix(release): publish local toolchain wrapper support

[rossirpaulo]

Summary

• bump the BAML wrapper from 0.2.3 to 0.2.4
• publish the local baml-cli path selection support merged in feat(toolchain): select a local baml-cli by path #4264

Root cause

The wrapper 0.2.3 release predates #4264. Because that PR changed wrapper behavior without advancing the independently versioned wrapper package, users on the latest wrapper still interpreted an absolute baml-cli path as a version and attempted to fetch a manifest for it.

Impact

The next wrapper release will support local toolchain selection with commands such as:

baml toolchain use ./target/release/baml-cli

Validation

• scripts/baml-wrapper-version check
• python3 -m unittest scripts.tests.test_release_pipeline_contract
• cargo check --manifest-path baml_language/Cargo.toml -p baml --release
• git diff --check
• pre-commit hooks

Poem

A bunny checks the crate tonight,
The version hops from three to four.
No new deps disturb the flight,
Just tidy metadata at the door.
