The new What’s New entries document session-tracking and dashboard improvements, but their heading level violates the documentation hierarchy and can fail Markdown linting. Update both headings to the appropriate sibling level before merge.

Use sibling ## headings for both new entries.

docs/src/content/docs/whats-new.md jumps to ### at Line 10, and markdownlint reports MD001. The second entry at Line 17 uses the same level, so changing only Line 10 would nest the second entry under the first. Change both headings to ##.
