Update to Deno 2.7.1 and remove unconditional Temporal unstable requirements

[dahlia]

Summary

This PR updates the repository to use Deno 2.7.1 and removes unconditional Temporal unstable-flag requirements where they are no longer needed.

• Bump pinned Deno version to 2.7.1 in mise.toml
• Update CI Deno setup version to 2.7.1
• Remove --unstable-temporal from root check tasks/config
• Remove root unstable.temporal usage
• Update @fedify/init generation logic:
  • Add "temporal" to unstable only when installed Deno is < 2.7.0
  • Omit unstable field when no unstable features are required
• Update docs/README:
  • Default Deno commands no longer include --unstable-temporal
  • Clarify that Deno < 2.7.0 still needs --unstable-temporal or unstable.temporal

Why

Since the Temporal API is stabilized in Deno 2.7, the previous unconditional unstable Temporal configuration is no longer necessary on modern Deno versions.

Validation

• mise run check:types passed
• deno check packages/init/src/action/configs.ts passed

Notes

This keeps backward compatibility for users on Deno versions earlier than 2.7.0 through conditional handling in fedify init.

Summary of Changes

Hello @dahlia, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request modernizes the project's Deno environment by upgrading to version 2.7.1 and adapting to the stabilization of the Temporal API. The changes streamline configurations by removing unnecessary unstable flags and introduce intelligent version-aware handling for the Temporal API in project initialization, ensuring compatibility across different Deno versions while leveraging the latest stable features.

Highlights

• Deno Version Update: The project's pinned Deno version has been updated to 2.7.1 across mise.toml and CI configurations, aligning with the latest stable release.
• Temporal API Stabilization: Unconditional requirements for the --unstable-temporal flag and the temporal entry in deno.json's unstable array have been removed, as the Temporal API is now stable in Deno 2.7.0.
• Conditional Unstable Flag Handling: The @fedify/init generation logic has been enhanced to conditionally add "temporal" to the unstable field only when the installed Deno version is older than 2.7.0, ensuring backward compatibility.
• Documentation Updates: Documentation and READMEs have been updated to reflect the removal of --unstable-temporal from default Deno commands and to clarify the conditional requirement for older Deno versions.

Changelog

• CHANGES.md
  • Changed fedify init to add "temporal" to deno.json's "unstable" field only when the installed Deno version is earlier than 2.7.0.
  • fedify init now omits the "unstable" field entirely when no unstable feature is required for the generated Deno project.

Code Review

This pull request updates Deno to version 2.7.1 and removes the now-unnecessary --unstable-temporal flag. The changes are consistent across configuration, documentation, and CI files. A key improvement is the new logic in @fedify/init to conditionally add the unstable flag based on the detected Deno version, ensuring backward compatibility. The implementation is robust, but I have one suggestion to improve debuggability in the version detection logic.
