Single Post Wide Centered Templates

[jasperf]

Version 3.8.0 introduces two new single post templates — single-centered.html and single-wide.html — expanding the available layout options for blog posts beyond the default single.html template. These templates give content editors a centered, constrained layout and a wide-format layout as selectable post templates in the block editor. The release also includes a responsive table overflow fix for post content, ensuring tables render correctly on mobile viewports. Version metadata has been updated across style.css, readme.txt, and CHANGELOG.md to reflect the 3.8.0 release.

New Post Templates:

• Added templates/single-centered.html and templates/single-wide.html as selectable single post layout templates, extending the WordPress template hierarchy with two distinct reading-width options.
• These templates follow the existing pattern-based architecture, each referencing a dedicated pattern slug via <!-- wp:pattern -->.

Bug Fixes:

• Fixed responsive table overflow in post content, preventing horizontal scroll bleed on narrow viewports where tables exceeded their container width.

Release and Documentation:

• Bumped theme version to 3.8.0 in style.css and readme.txt (Stable tag).
• Added corresponding changelog and readme entries documenting the new templates and the table overflow fix.

Files Changed:

• CHANGELOG.md (Modified)
• readme.txt (Modified)
• style.css (Modified)
• templates/single-centered.html (Added)
