Summary

This PR optimizes the CI and Release GitHub Actions workflows by creating a reusable composite action and consolidating redundant jobs.

Changes

New Composite Action

  • Created .github/actions/setup-go-wt for reusable setup steps
  • Consolidates token generation, checkout, and Go setup into a single reusable action
  • Enables Go module caching for faster builds

CI Workflow Optimizations

  • Reduced from 627 to 492 lines (-21.5%)
  • Consolidated build and cross-compile into single job
  • Removed Go 1.24 testing matrix (focusing on latest 1.25)
  • Applied composite action to all 7 jobs (lint, test, build, e2e-macos, e2e-linux, e2e-windows)
  • Improved job ordering following best practices: lint → test → build → e2e

Release Workflow Optimizations

  • Reduced from 283 to 224 lines (-20.8%)
  • Consolidated build and build-windows into single matrix job
  • Applied composite action to build and release jobs
  • Simplified dependency graph

Benefits

  • Maintainability: Single source of truth for setup logic - changes only need to be made once
  • Performance:
    • Go module caching reduces build times significantly
    • Removed duplicate Go 1.24 testing saves ~5-7 minutes per CI run
    • Consolidated build jobs reduce workflow complexity
  • Consistency: All jobs use identical setup process, reducing drift
  • DRY Principle: Removed 21 redundant setup steps across both workflows
  • Total reduction: 159 lines removed (-27.7%)

Testing

The optimized workflows follow Go CLI best practices:

  • CI Pipeline: lint → test → build → e2e tests (parallel across OS/shell)
  • Release Pipeline: build all platforms → create release → update package manager

Optimize e2e test jobs to use binaries from the build job instead of rebuilding them:

- Build job now uploads platform-specific artifacts (linux, macos, windows)
- E2E jobs depend on build job and download appropriate artifacts
- Eliminated 6 redundant builds (2 per OS)

Benefits:
- Saves 3-6 minutes of total CI time
- Ensures e2e tests use exact binaries verified in build job
- Reduces compute resource usage
- Clearer dependency graph

Add job dependencies to ensure proper execution order:
- Build job now depends on lint and test passing
- E2E jobs already depend on build (from previous commit)

Execution flow:
  Lint ──┐
         ├──> Build ──> E2E Tests
  Test ──┘

Benefits:
- Fail fast: Don't waste resources building if quality checks fail
- Resource efficiency: Build only runs when necessary
- Clearer pipeline: Explicit dependency graph shows execution order
- Faster feedback: Issues caught in lint/test stop pipeline immediately

Changes:
- Test job now runs only unit tests with `-short` flag
- Renamed job to "Unit Tests" for clarity
- Removed shell installation (bash/zsh) - not needed for unit tests
- E2E tests with PTY/shell interaction remain in dedicated E2E jobs

Test categorization:
- Unit tests (main_test.go, shellenv_test.go): Run in Test job with -short
- E2E tests (e2e_test.go, e2e_interactive_test.go): Run in E2E jobs on specific platforms

Benefits:
- Faster Test job (~30-60 seconds saved from skipping e2e tests)
- No redundancy: E2E tests only run once in platform-specific jobs
- Clearer separation: Unit tests vs Integration/E2E tests
- Simpler Test job: No shell installation needed

Move dependency verification from Unit Tests job to Lint job:
- Provides earliest possible failure point for dependency issues
- Lint job now checks: dependency integrity + code quality
- Unit Tests job simplified to just running tests

Benefits:
- Faster failure detection for corrupted/modified dependencies
- Logical grouping: pre-build validation checks in one job
- Cleaner separation of concerns

Remove unnecessary abstraction layer:
- Deleted .github/actions/setup-go-wt (minimal value)
- Updated all 9 jobs to use actions/setup-go@v5 directly
- Kept Go caching enabled in all jobs

The composite action was just a thin wrapper around setup-go with cache enabled, which doesn't justify the extra abstraction. Direct usage is clearer and simpler.

Changes:
- ci.yml: 6 jobs updated
- release.yml: 3 jobs updated

Update settings.yml to reflect the streamlined CI workflow:

Removed:
- "Test (1.24)" - no longer testing multiple Go versions
- "Test (1.25)" - consolidated to single test job
- "Cross Compile" - merged into build job

Updated:
- "Build" → "Build and Cross-Compile"
- "Test" → "Unit Tests"

Required checks now:
- Lint (includes go mod verify)
- Unit Tests (go test -short)
- Build and Cross-Compile (all platforms)

- E2E Tests (Linux): bash, zsh
- E2E Tests (Windows): powershell, pwsh

This ensures all platform and shell combinations must pass before merge.
