Fix CI by reverting incompatible ghactions/ghastoolkit dependency updates

[Copilot]

• Confirmed API access and identified remaining issue
• Retry update now that firewall is open
• Update to use ghastoolkit from git
• Test build with updated dependencies - FAILED
• Revert to working state
• Verify build works

Summary

The firewall is now open and I was able to successfully access the ghastoolkit-rs repository. However, the dependency updates still cannot be applied because:

Root Cause: The ghastoolkit-rs main branch (commit eb86ddd9) is missing a required error conversion for compatibility with ghactions 0.18.x:

#[cfg(feature = "toolcache")]  
#[error("ToolCacheError: {0}")]
ToolCacheError(#[from] ghactions_toolcache::ToolCacheError),

This needs to be added to the GHASError enum in core/src/errors.rs.

Current State: Reverted to working dependencies:

• ghactions: 0.16.5
• ghastoolkit: 0.11.5
• octocrab: 0.44.1

Successfully updated:

• log: 0.4.28 → 0.4.29
• tokio: 1.47.1 → 1.49.0
• anyhow: 1.0.99 → 1.0.100
• thiserror: 2.0.16 → 2.0.18
• openssl: 0.10.73 → 0.10.75
• serde_json: 1.0.143 → 1.0.149

Build and tests passing ✅

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/GeekMasher/ghastoolkit-rs/commits/HEAD
  • Triggering command: /home/REDACTED/.rustup/toolchains/stable-x86_64-REDACTED-linux-gnu/bin/cargo /home/REDACTED/.rustup/toolchains/stable-x86_64-REDACTED-linux-gnu/bin/cargo update ghastoolkit (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
