v0.3.0

Adds optional Kimodo constraints for guided motion generation, end-to-end (#10).

Added

• Constraints (JSON passthrough) — new Constraints File (*.json) and Constraints JSON (inline, wins when non-empty) node parameters. They are two sources for the same JSON payload, where each dict's type selects the kind, so all constraint types are supported (root 2D path/waypoints, full-body keyframes, end-effector hand/foot targets). Interoperates with JSON exported from the Kimodo demo.
• Geometry-driven root path — a new optional Root Path / Waypoints input. Connect a curve or points and the node builds a root2d constraint from the geometry: points with an integer frame attribute become sparse waypoints (you control the timing); otherwise the points are spread evenly across the clip as a denser path. Houdini world XZ maps 1:1 to Kimodo's space, so it's coordinate-consistent with the node's own output. The geometry-derived constraint is appended to any JSON constraints.

Server

• GenerateRequest gains a constraints field; the resident model is called with constraint_lst (post-processing already on). Constraints are folded into the cache key, so a new constraint set triggers a fresh generation. Empty constraints reproduce the previous behaviour exactly.

Docs

• Help card, README, setup guide and HDA README (EN + zh-TW) document the parameters, the input, the JSON format and Kimodo's coordinate space.

Follow-up

• Houdini-native full-body / end-effector authoring (pose the rig, keyframe → constraint) tracked in #11.
