Fix coverage generation failure with missing app files (Issue #83) (#85)
* fix: Resolve coverage generation failure with missing app files - Add --exclude 'app/*' to gcovr command to avoid missing debug_subplot.f90 - Add graceful fallback for gcovr processing issues common with FPM projects - Clean both .gcda and .gcno files to prevent stale coverage metadata - Improve error handling with informative warning messages Fixes #83 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * test: Add coverage workflow validation test - Add simple test to verify coverage generation works correctly - Test exercises basic functionality for coverage analysis - Ensures coverage system doesn't crash with new exclusions Related to #83 * fix: resolve critical CI failures blocking PR merges - Fix line length violation in fortplot_figure_core.f90 (132 chars -> 88 char limit) - Restore CMakeLists.txt required for CI cmake builds - Autonomous fix during batch mode PR processing to enable merging 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>
