docs(vterm): record the deleted framing/tab-width branches

vterm-stage3-framing (superseded; content carried on vterm-gpu) and
tab-width-parity (merged via #137) were deleted with authorization —
worktree + local ref + githubsucks ref, origin tracking pruned. The
-framing branches for each are kept. Retires the now-dangling
