v0.1.11

fix(usage): skip mid-render polls, respawn meta on stuck reads

• Detect when claude's /usage view is still rendering ('Loading usage
  data…' without bars) and return an empty snapshot instead of inserting
  garbage. The dashboard then keeps the last known good value rather
  than dropping to whatever the loading placeholder leaves behind.
• Hash each successful parse and track consecutive identical reads.
  After 3 in a row, kill the meta-process so the next poll fetches a
  fresh /usage from the server. Ported from agent-view's stuck
  detection — covers the case where claude serves a cached view.
• Send Cache-Control: no-cache on the served index.html (assets stay
  immutable since they're content-hashed) so Wave's webview stops
  loading stale dashboard bundles after each release.
