fix: keep patch release details inline with each fix

[hannesrudolph]

What Problem This Solves

Patch release notes repeat a full-width details row after every fix, making the list harder to scan.

User Impact

An opt-in native “More details” control follows the fix sentence instead, while PR links and thanks remain expandable and keyboard-accessible.

Why This Change Was Made

Add a scoped inline layout for the existing release-source disclosure. Keep its native toggle, focus indicator and 44px touch target; ordinary disclosures are unchanged. No parser or JavaScript changes.

This is the renderer dependency for the 10.4 notes draft. Neither PR is authorized for merge or live publication by this presentation request.

Evidence

• Focused Chromium test passes at desktop and narrow widths, checking same-line placement, no horizontal overflow, click/Space/Enter toggling and Tab/Shift-Tab source-link access.
• Independent review found no blockers. Existing prose, sections, links, credits and release facts are unchanged.
• The rebuilt native Studio preview uses release source 35f1facdccf and renderer 263e8efecd7; desktop inline-flow, keyboard and no-overflow checks passed. Earlier proof is retained.
