feat(releases): add v3.10 in-app release notes

[ThisIs-Developer]

What changed

• Restored the release-note implementation to commit 6561fe3 as requested.
• Kept the extensionless RELEASE_NOTES source and the existing v3.10.0 in-app release-note lifecycle.
• Disabled Export, Share Snapshot, and Live Share while the Release Notes tab is active on desktop and mobile.
• Prevented those actions from being triggered programmatically while Release Notes is active, and restored their prior state after switching to a regular document.
• Moved Apache License 2.0 above Show Release Notes in About Markdown Viewer.
• Added a small amount of space above the release label and changed it to Markdown Viewer release · v3.10.0.
• Rebuilt the synchronized Neutralino desktop resources.

Why

Release Notes is an application-owned, read-only tab rather than a user document. Document export and collaboration actions should therefore be unavailable there, while the About menu and release heading should follow the requested presentation.

Validation

• Focused Playwright release-note behavior test: 1/1 passed.
  • verified desktop and mobile Export, Share Snapshot, and Live Share controls are disabled;
  • verified programmatic activation cannot open export/share/live-share dialogs;
  • verified the controls restore after leaving Release Notes;
  • verified the About menu order and 8 px release-label top spacing.
• npm run build passed.
• Translation audit passed: 14 catalogs × 1170 keys.
• JavaScript syntax checks passed for the web and generated desktop scripts.
• Root and generated desktop release-note, script, and stylesheet files match.
• Responsive toolbar checks passed at 320, 375, 768, 1080, and 1440 px.
• git diff --check passed.

One pre-existing local toolbar assertion still expects version 3.9.3 and the former Changelog menu item; the remaining 7/8 assertions passed. This requested update does not change that stale test fixture.

User impact

Users can read and navigate the v3.10.0 Release Notes normally, but document-only export and collaboration commands are clearly unavailable until they return to a regular file. The About menu and release heading now use the requested order and spacing.
