Harden avatar selection and loading for posecode#124

…uts (#126)

Bumps changesets/action from v1 to v2 and updates the release workflow to the renamed v2 inputs (version-script, publish-script, commit-message, pr-title, create-github-releases) plus the explicit github-token input.

…ectory with 12 updates (#128)

Dev-dependency bumps plus the CI Node 24 upgrade required by @changesets/cli v3, and an empty changeset.

…y with 4 updates (#129)

Bumps @modelcontextprotocol/sdk, vscode-languageserver-textdocument and the CodeMirror runtime packages, with a patch changeset for posecode-mcp.

Releases posecode-parser, posecode-render, posecode-share, posecode-embed and posecode-mcp 0.4.3.

avatar2.glb and avatar3.glb are Adobe Mixamo exports (the Beta and Remy
characters): both carry the mixamorig: skeleton, a mixamo.com animation track,
and Mixamo mesh and texture names. List them alongside xbot.glb so the existing
Mixamo posture covers every committed character, and sync package-lock.json with
the 0.4.3 workspace versions.

Support document-selected avatar appearances alongside the humanoid rig

The release branch is pushed with GITHUB_TOKEN, so GitHub does not dispatch
workflows for it and the required Build & Test check never runs.
