kill: purge old-paradigm dist/platform binaries from tree

The generated C, amalgams, vendored runtime pins, and compiled binaries
from the Claude Code era are removed from the worktree. The El sources
survive; this tree is now source-only for the first-principles rebuild.

Per Principal direction 2026-08-19.
