Patterplay JS 0.1.0

Added

• The Patter runtime in JS/TS: Engine + Flow over a compiled .patterc bundle - scenes,
  blocks, run/choice/branch/sequence selectors, sticky/fallback options, call-return jumps,
  conditions + effects, visit counts, {@ref} interpolation, game events, tags, gameData
  merge-at-read, and whole-game save/load (saveGame / loadGame).
• The patterplay.min.js drop-in: the whole runtime as one self-contained <script> file
  (window.Patterplay), for plain HTML pages with no bundler.
• Localisation: play any locale of an Embedded bundle, switch live with setLocale, or ship
  an IDs-only bundle and localise in your own system (flow.interpolate). Closed-caption cue
  stripping via setClosedCaptions.
• Live refresh: replaceStrings (text-only edits, in place) and hotSwap (structural edits,
  state carried over) - the engine side of Patterpad's Live Link hot reload.
• Structure introspection: getOutline() / getBeatSequence() expose the authored tree
  (per-beat text, character, gameData, tags) for tooling.
• Companion helpers live in @patterkit/play-helpers (save envelopes, property setters,
  state logger, Live Link client, property inspector, audio resolution).
• Distribution: patterplay-js-<version>.zip on each play-js-v* GitHub Release (the
  runtime + module builds + two demos, no npm needed), npm, and the CDN drop-in - all the
  same version.
