feat(linter): align Super-Linter defaults with workflow behavior

[Copilot]

The reusable linter workflow now produces Super-Linter summaries without warnings while keeping commit message validation enabled for repositories that do not provide their own commitlint configuration.

What changed

Summary handling

• Default SAVE_SUPER_LINTER_SUMMARY to true so the configured GitHub step summary and pull request summary paths are consistent with Super-Linter's requirements.
• Preserve caller overrides supplied through linter-env.

Opinionated commitlint fallback

• Keep Super-Linter's commitlint validator enabled by default.
• Detect commitlint configuration in supported .commitlintrc* and commitlint.config.* files, or in the root package.json.
• Generate a temporary commitlint.config.cjs with the repository's Conventional Commits rules only when commitlint is enabled and no caller configuration exists.
• Preserve an explicit VALIDATE_GIT_COMMITLINT=false override.
• Normalize an explicit VALIDATE_GIT_COMMITLINT=true back to Super-Linter's enabled-by-default behavior, avoiding its unsupported mix of include and exclude validator flags.
• Return the generated configuration's absolute path as a step output and remove that exact file after Super-Linter finishes, including on failure.

Workflow structure

• Separate Super-Linter environment configuration, commitlint fallback configuration, and Prettier plugin discovery into focused sequential steps.
• Keep the existing conditional Node.js setup for repositories that declare Prettier plugins.

Validation

• make lint

Addressed in 1bbd99a: commitlint is enabled again, the workflow now writes an opinionated fallback config when none exists, and the generated file is cleaned up afterward.

@copilot now the job is failing:

Super-Linter initialization
2026-08-31 06:50:03 [ERROR] Behavior not supported, please either only include (VALIDATE=true) or exclude (VALIDATE=false) linters, but not both
2026-08-31 06:50:03 [FATAL] Error while validating the configuration of enabled linters

Fix that

@copilot now the job is failing:

Super-Linter initialization...

Fixed in 076ec3c. The workflow no longer exports a conflicting VALIDATE_GIT_COMMITLINT=true flag, so Super-Linter keeps its default commitlint behavior without tripping the include/exclude validator conflict.
