index: keep Research, Volunteer and Sample; drop the rest

Removes the Blog, Vibe Coding, and GNUstep & Gershwin Guides sections --
11 entries -- leaving Research at the top, followed by Volunteer Projects
and Sample Projects.

Only the index listing changes. All 11 HTML pages stay in the repo and at
their URLs, so existing deep links keep resolving; they are simply no
longer surfaced from the front page.

Four pure virtuals, ~1,000&ndash;2,000 lines of Objective-C++, and the traps that cost someone a day each in 1993: the update deadlock, the bitmap format flag, the XOR cursor. Why per-window <code>NSWindow</code>s are impossible and rootless works anyway.</span>

The <code>VideoDriver</code> contract, the threading and deadlock rules, pixel formats, the libobjc2 toolchain traps, the GNUstep API gap tables, why the nibs can't be opened, and why <code>HFS_XFer</code>'s HFS engine is dead code.
