rqualify

Major changes

• Qualification now requires a successful subprocess exit and an explicit PASS completion result.
• Summary checking now validates all eight expected suites, required columns, allowed statuses, and consistency with available execution evidence. Missing or malformed summaries cannot establish a successful qualification.
• Added details = TRUE to rqualify() to return overall status, per-suite evidence, report paths, timestamps, and R/tool versions. These results are also saved as validation_result.rds; the default return remains the output directory path.
• Quarto uses its bundled Pandoc and Typst without checking for or installing TinyTeX or standalone Pandoc. The selected R executable is passed to Quarto explicitly.
• Invalid engines, logical arguments, and output paths are rejected before setup. Dependency checks precede directory creation, allowing retries after a missing prerequisite is resolved.

Minor changes

• Fixed the Windows CI test for TinyTeX PATH activation to use the native path separator and executable name.
• Both report formats now share execution and result-classification functions. Subprocess scripts and logs are retained, and paths containing spaces or quotes are handled safely.
• Added regression tests for subprocess failures, malformed summaries, engine-specific prerequisites, retries, tool discovery, and structured results. Added opt-in PDF rendering smoke tests for both templates and a dedicated CI workflow using short failure fixtures.
• Expanded test coverage for tool-version metadata, all six package test suites, subprocess diagnostics, template and directory failures, and missing renderers.
• Clarified that core system tests use scope = "basic"; development and internet scopes are not run. Updated the templates, function documentation, and vignettes to describe the actual checks and results.
