We don't have a self hosted runner for x86_64-linux at the moment

…tions

Replace always() with !cancelled() to prevent jobs from running when the workflow
is cancelled. Add explicit success/skip conditions for dependent jobs to ensure
proper workflow execution flow.

We couldn't set duration to 18000 seconds when chaining roles.

Refactor GitHub Actions workflow to run build checks in parallel across different
architectures (aarch64-linux, aarch64-darwin) with separate job matrices.

Create a single nix-eval job to determine packages to build, removing
redundant extension and check matrices.

This reverts commit e2db368.

This cause unnecessary rebuilds on every commit.

When building a postgres extension, the build matrix may include
multiple time the same extension for different PostgreSQL versions.
This change makes it easier to identify which job corresponds to which PostgreSQL
version in the workflow runs.

treefmt is already included in the pre-commit hooks check.

Dynamically assign larger runners (32vcpu) for Rust and PostGIS extensions
while using smaller runners (8vcpu) for standard packages.

Add pytest tests for the package
Add nix-eval-jobs in path for the package

The matrix job returns the type of runner, so we can configure the nix
installation step accordingly.
