v4.1.10

Fixes

• Use native macOS open -a for named browser launches so Chrome opens in the foreground.
• Allow valid filenames containing double dots, such as index..html, while still rejecting actual parent-directory path segments.
• Debounce live-reload dirty-buffer snapshots so typing does not copy the entire buffer on every keystroke.

Verification

• python3 -B -m unittest tests.test_regressions
• Syntax compile check for touched Python files
• git diff --check
