chore: release 3.1.0

[Gamote]

Version bump only. 3.1.0 carries, since 3.0.0: configureLottie with element IDs prefixed by default and the widened rendererSettings types (#137), the client-module directive on the public browser-only modules (#138), the scroll scrub under overflow-x: hidden (#134), the live context.lottie for interaction factories (#136), and the docs pass (#135). Gate green at this tree (488 tests, coverage 100 / 97.46 / 100 / 100, 36 pages); pnpm check:package loads all 20 exports through require() and native ESM.

After the merge: tag v3.1.0 on the merge commit, publish, GitHub release, website deploy.
