feat(capture): OCR region to clipboard (LATER item)

Tools › Capture gains "OCR region → clipboard", self-gated on
tesseract: slurp the region (Esc cancels silently, the recording.nix
pattern), grim it, tesseract stdin→stdout, wl-copy. Whitespace-only
recognition toasts "No text recognized" instead of clobbering the
clipboard; success toasts the word count. tesseract ships English-only
through the menu's package set — the unscoped wrapper pulls every
language's traineddata, a real cost on a compile-from-source distro;
overriding with more languages is documented at the package line.

Verified: V0; V1 — template-home builds with the gated row + case and
menu bash -n; functional — the profile's own tesseract read a rendered
test image back verbatim, proving the OCR half of the pipe. The
grim/slurp half needs a session → HARDWARE-QUEUE.
