Adds renderer-spec §7.9 and wires it into the existing capability sections instead of a standalone feature spec: pointer shape is one more consumer of RuntimeCapabilities, gated the same way as the rest. - §7.9: open() gains pointerShape (kitty/CSS shape names; anything else is ignored and never reaches output). While capabilities.pointerShape is true, the last declaring element in hit-test order wins (innermost; capture-mode floats hide what is beneath, passthrough floats defer to it). Changes are appended to result.output as OSC 22 ; <shape> ST, so the host keeps writing one buffer (cowboyd on #101, replacing #101's separate result.cursor). There is no createTerm opt-in: the capability is the only gate. - Restore (dreyfus92 on #101): set-only OSC 22 cannot pop, so the Term sets "default" when the pointer leaves or is omitted, and update() returns the reset when the capability is withdrawn. Resize keeps the emitted shape since the terminal pointer is unaffected. - §7.3: output "may be" a view, since a frame carrying OSC 22 is assembled in TypeScript. - §7.7, §7.8, §11.2, §12.2 and terminfo-spec §6.3/§9.3 point at §7.9 instead of a "focused feature specification". terminfo-spec §6.3 documents the escape hatch for set-only terminals that never answer the query: term.update([{ type: "capability", key: "pointer-shape", value: true }]). "pointerShape" rather than "cursor": cursor already names the hardware text cursor (§7.6), and pointerShape matches the capability key and RuntimeCapabilities field.
