v2.60.0

Every file build writes is byte-identical to v2.59.0's

Three additions, none of which changes what build emits:

• rigc review <dir> [...] hands a build to a person. It runs the rig-review bin of @rig-c/review with the arguments untouched and returns its exit code. When the package is not installed, it refuses by name: npm i -D @rig-c/review. @rig-c/review is not a dependency of rig-c.
• rigc render --seam <a>:<b>[,…] is a reading, never a gate: it does not move the exit status. It writes seam.json (rigc-seam/1) beside each rendered set, reporting per frame where two slots that meet open a gap or show a ghost. Each entry gives frame index, time, px and a Spine-world box, plus spans and the worst frame. The contract is AUTHORING §8.8.
• The stops half-turn refusal (CE_STOP_LOCAL_BOUND_RANGE) now names the link, its root, the touch's world position, rest, the end, and the remedy. The code and the old text, now a prefix, are unchanged.

Features

• cli: rigc review delegates to the installed @rig-c/review bin (#1462) (70ecefa)
• render: render --seam — per-frame seam gap and ghost between two slots, a reading that never moves the exit status (#1464) (24b4714)

Bug Fixes

• stop: name the link, the point and the remedy when a first-link bound passes a half turn (#1460) (3886df5), closes #1455
