test: Add placeholder test files for comprehensive script coverage

Ensures every .js file in scripts/ has corresponding .test.js file in __tests__ subfolder.
This establishes complete test coverage structure across the codebase.

Created tests for:
- Agent scripts (3 files): generate-plugin, release, release-scaffold
- Lib scripts (6 files): config-schema, logger, mode-detector with full and targeted tests
- Utils scripts (9 files): audit-frontmatter, check-markdown-references, count-tokens, fix-instruction-references, scan-mustache-variables, update-version, components, entry, hooks, test-placeholders
- Validation scripts (5 files): validate-mustache-registry, validate-plugin-config, validate-block-json, block-json, block-schema
- Root-level scripts (13 files): agent-script, audit-frontmatter, build, count-tokens, dry-run-config, dry-run-test, scan-mustache-variables, test-dry-run, test-mustache-schema, test-placeholders, update-version, validate-mustache-registry, validate-plugin-config

Total: 38 test files created/modified

Each test contains placeholder structure with TODO comments for implementation.
Tests follow Jest conventions with __tests__ subdirectory organization.
