Fix rustdoc nightly build: Replace doc_auto_cfg with doc_cfg

[ishanrajsingh]

Fixes #1166

Summary

Updates the rustdoc feature flag from the deprecated doc_auto_cfg to doc_cfg.

Background

The doc_auto_cfg feature was merged into doc_cfg in Rust nightly as part of RFC 3631 (rust-lang/rust#138907). The old feature name is no longer available and causes compilation errors.

Changes

• Updated src/lib.rs line 34 to use feature(doc_cfg) instead of feature(doc_auto_cfg)

Testing

• Verified locally by running ./test.sh successfully
• All tests pass including doc generation

Code Review

This pull request correctly addresses a build failure on Rust nightly by updating the deprecated doc_auto_cfg feature to doc_cfg. The change is simple, well-explained, and necessary to maintain compatibility with the latest toolchain. The fix is accurate and I see no further issues.

Thanks for the PR! Could you update the version to 0.2.3-dev and add an appropriate entry in the Changelog? Otherwise I'll do it tomorrow.

Hi @ia0 , I have made the updates mentioned

Changelog and version updated

Thanks! This looks good, but technically we need to propagate the change to the CLI too, which means:

• Change the dependency in cli/Cargo.toml to =0.2.3-dev.
• Change the CLI version to 1.0.1-dev.
• And update the CLI changelog with - Update dependencies as a patch-level update.

You'll also need to update the Cargo.lock files. The simplest way to do it is run ./test.sh from the rust directory.
