Add `width="100%"` to every HTML content and contributor table across all
project READMEs so they render full-width on GitHub instead of collapsing
to natural content width. Cell-level `width="X%"` percentages were already
in place but only take effect once the table itself has an explicit width.
Also update the contributor-sync scripts so the auto-generated tables stay
consistent on the next bot run:
- .github/workflows/contributors/generate_main_readme.py
- .github/workflows/contributors/generate_readme_tables.py
Scope: 27 files, 85 tables. Sub-project READMEs that already use the
"card" pattern (labs/, kits/ content sections with <table width="98%">
wrappers) are intentionally untouched.
Standardize table formatting across 25 README files to use
HTML tables with consistent styling (thead/tbody, column widths,
bold labels) matching the main README's presentation.
