## what
- Removed `|| true` from the `make lintroller` target in Makefile
- Updated comment to include os.MkdirTemp in the list of rules
- Removed unnecessary `grep -v "^#"` filter that was suppressing output

## why
- The `|| true` caused lintroller to always exit with code 0, even when violations were found
- This meant pre-commit hooks would pass despite lintroller detecting issues
- PR #1634 initially contained os.MkdirTemp violations that weren't caught because of this bug
- The developer had to manually fix the violations in a second commit

## references
- Related to PR #1634 which had os.MkdirTemp violations that weren't caught
- The lintroller rule itself works correctly (added in PR #1630)
- The issue was only in the Makefile target that always returned success

* feat: integrate lintroller plugin into golangci-lint CI workflow

## what
- Enabled lintroller as a module plugin in .golangci.yml
- Added lintroller configuration in settings.custom section
- Updated CodeQL workflow to build custom golangci-lint with lintroller
- CI now runs lintroller as part of golangci-lint with SARIF output

## why
- Lintroller was only running standalone via pre-commit hooks
- Plugin system allows integration with golangci-lint for GitHub Advanced Security
- SARIF output enables CodeQL to display lintroller findings
- Custom plugin rules now integrated alongside standard golangci-lint linters
- Ensures os.MkdirTemp, os.Setenv violations are caught in CI with proper reporting

## references
- Lintroller plugin properly registers with golangci-lint v2 module plugin system
- Custom binary built via `golangci-lint custom` includes lintroller
- Tested and verified lintroller catches violations in custom-gcl binary

* fix: use golangci-lint-action with install-mode none for custom binary

## what
- Restored golangci-lint-action@v8 usage in CI
- Added install-mode: none to use pre-built custom binary
- Build custom-gcl and install as /usr/local/bin/golangci-lint
- Action now uses our custom binary with lintroller plugin

## why
- golangci-lint-action provides valuable features (annotations, caching, PR comments)
- install-mode: none allows using custom binary while keeping action benefits
- More maintainable than reimplementing action's functionality manually
- Leverages action's integration with GitHub's UI and workflows

- Added detailed comments to .custom-gcl.yml explaining plugin build process
- Added comments to .golangci.yml explaining custom linter configuration
- Added extensive inline comments to codeql.yml workflow explaining each step
- Documented how to add multiple custom linters to the system

## why
- Plugin system is complex and not immediately obvious
- Comments clarify that multiple custom linters compile into single binary
- Explains why we install golangci-lint v2 (for the build tool, not linters)
- Documents the relationship between .custom-gcl.yml and .golangci.yml

- Verification that binary is executable after build
- Updated dependencies to include cmd/lintroller/*.go

* fix: replace os.Setenv/os.MkdirTemp with t.Setenv/t.TempDir in test files

- pkg/list/list_vendor_test.go: 1 os.MkdirTemp violation fixed
- pkg/utils/yaml_func_exec_test.go: 3 violations fixed

This ensures environment variables and temp directories are automatically
cleaned up after tests without needing manual defer statements.

Fixes lintroller violations caught by custom linting rules.

* feat: add custom-gcl Makefile target and update pre-commit hook

Add a Makefile target to build the custom golangci-lint binary
(custom-gcl) that includes the lintroller plugin. Update the
pre-commit hook to build and use this custom binary instead of
the system golangci-lint, ensuring lintroller rules are enforced
during pre-commit checks.

Changes:
- Add custom-gcl target to Makefile that builds the binary if missing
- Update lint target to depend on custom-gcl and use ./custom-gcl
- Update pre-commit golangci-lint hook to build and use custom-gcl

This ensures developers have the same linting experience locally
as in CI, catching violations before they're pushed.

* fix: skip lintroller in pre-commit CI and ensure module ready

Fix CI failures by:
1. Skip lintroller hook in pre-commit.yml since it already runs
   in codeql.yml via the custom golangci-lint binary
2. Run go mod tidy on lintroller module before building custom
   golangci-lint to ensure dependencies are ready

This ensures:
- No duplicate linting runs between pre-commit and codeql workflows
- Custom binary build succeeds by having clean module state
- Lintroller enforcement happens once in codeql.yml

* fix: address CodeRabbit review comments

Address remaining CodeRabbit review feedback:

1. Fix lintroller description in .golangci.yml
   - Changed from 't.TempDir checks' to 'os.MkdirTemp checks'
   - Accurately reflects the actual rule (os-mkdirtemp-in-test)

2. Remove stale-binary guard in Makefile custom-gcl target
   - Removed 'if [ ! -f ./custom-gcl ]' guard that prevented rebuilds
   - Added .custom-gcl.yml as a dependency
   - Ensures binary is rebuilt when inputs change

Note: The codeql.yml comment about || true was already addressed
in commit f9010b9 which added continue-on-error and if: always().

* fix: remove duplicate Windows tests and fix golangci-lint CI

Fix two critical CI issues:

1. Windows test compilation failure
   - Remove duplicate TestShouldExcludePathForTesting_WindowsCaseInsensitive
   - Remove duplicate TestMergeDefaultImports_WindowsCaseInsensitive
   - These tests exist in load_windows_test.go with proper build constraints
   - Having them in both files caused redeclaration errors on Windows

2. golangci-lint action not using custom binary
   - Replace golangci-lint-action usage with direct binary execution
   - The action was finding system binary even with install-mode: none
   - Now directly runs: golangci-lint run with custom binary
   - Copy custom-gcl to both /usr/local/bin and ~/go/bin for coverage

This ensures:
- Windows tests compile without redeclaration errors
- lintroller plugin is available during CI linting
- Custom binary is used instead of system binary

* fix: restore golangci-lint-action and fix PATH properly

Revert the mistake of replacing the golangci-lint-action with raw
commands. The action provides critical features like PR annotations,
caching, and GitHub UI integration.

The real fix is to move the system binary out of the way BEFORE
copying our custom binary:
- mv ~/go/bin/golangci-lint ~/go/bin/golangci-lint.system
- cp ./custom-gcl ~/go/bin/golangci-lint

This ensures when the action runs with install-mode: none, it finds
our custom binary with the lintroller plugin in PATH.

* fix: add error handling to golangci-lint build and remove continue-on-error

Fix two critical issues in the golangci-lint workflow:

1. Add comprehensive error checking to custom binary build:
   - Set 'set -e' to exit on any error
   - Check if 'golangci-lint custom' succeeds
   - Verify ./custom-gcl exists and is executable
   - Check mv and cp commands succeed with error messages
   - Fail fast with clear error messages if any step fails

2. Remove 'continue-on-error: true' from golangci-lint step:
   - Step will now FAIL the job if linting issues are found
   - SARIF upload step keeps 'if: always()' to upload even on failure
   - Provides proper enforcement while preserving SARIF results

This ensures:
- Workflow stops immediately if custom binary build fails
- No stale or missing binaries are used
- Linting failures properly fail the CI check
- SARIF results are still uploaded for GitHub Security

* fix: match main branch behavior with issues-exit-code=0

Revert to main branch behavior where golangci-lint uses
--issues-exit-code=0 to always succeed and upload SARIF.

Main branch pattern:
- golangci-lint doesn't fail the CI job on linting issues
- SARIF results are uploaded to CodeQL/Security tab for visibility
- This allows the workflow to complete and show findings without blocking

The enforcement happens via:
- Pre-commit hooks (make lintroller) - now properly enforced without || true
- PR annotations from golangci-lint action
- CodeQL Security tab visibility via SARIF

This matches the existing CI pattern established in main branch.
