📝 Walkthrough

Walkthrough

The project now targets Rust 1.96.1 and Alpine 3.24. CI, release workflows, documentation, and test images use the updated versions. Docker test images install go-task from Alpine packages. The noinit image removes manual act installation.

Changes

Toolchain and test environment refresh

Layer / File(s)	Summary
Rust toolchain alignment Cargo.toml, rust-toolchain.toml, Makefile, README.md, .github/workflows/*.yml	Project configuration, workflows, and installation instructions now use Rust 1.96.1.
Builder image and test runner updates tests/Dockerfile.builder, tests/docker_unit/Dockerfile, tests/run_tests.sh	The builder image uses Rust 1.96.1 and Alpine 3.24. The unit image uses dela-builder. The test runner builds the image when it is not configured or available locally.
Integration test image updates tests/docker_*/Dockerfile, dev_docs/testing.md	Integration images use Alpine 3.24 and install go-task through Alpine packages. The noinit image removes manual act installation. Documentation reflects Alpine 3.24.

Poem

A rabbit checks the toolchain tune,
Rust and Alpine rise with the moon.
go-task joins each test-built trail,
Old image steps leave no detail.
The builder hops when images fail.

Verify each finding against current code. Fix only still-valid issues, skip the

Inline comments:
In `@Cargo.toml`:
- Line 4: Update the Rust toolchain versions in the CI workflows rust.yml and
release.yml from 1.93.0 to 1.96.1, matching the project’s rust-version and
rust-toolchain.toml requirements.

In `@README.md`:
- Line 23: Remove the shell prompt marker from the changed cargo installation
command and the adjacent dela init command in the README command block, leaving
only the executable commands.

In `@tests/docker_unit/Dockerfile`:
- Line 5: Update the direct unit-test runner flow in run_tests.sh so it builds
or otherwise ensures the dela-builder image exists when BUILDER_IMAGE is unset,
matching the existing make test_unit and CI behavior before using
tests/docker_unit/Dockerfile. Preserve support for explicitly provided
BUILDER_IMAGE values.
