v0.18.0

Release notes from CHANGELOG.md for @async/framework@0.18.0 (2026-07-08).

• BREAKING: unified lifecycle vocabulary on "attach" and removed the "mount"
  term everywhere. loader.mount(...) and the Async.loader.mount(...)
  facade are now loader.attach(...) / Async.loader.attach(...); the
  rendered-component mount(target) alias is gone (use attach(target));
  this.on("mount", ...) now throws (use this.on("attach", ...)) and the
  this.onMount(...) helper was removed (use this.onAttach(...)); the
  on:mount markup alias no longer binds; stale markup logs a one-time
  removal warning. The Flow bridge feature key mountRegistrations is now
  attachRegistrations (attachFlowRegistrations). Specs, docs, and type
  declarations use attach terminology throughout.
• Bundle size from bundled TypeScript source: browser.ts raw 261,003 B (261.0 KB / 0.261 MB), gzip 49,799 B (49.8 KB / 0.050 MB), br 41,084 B (41.1 KB / 0.041 MB) -> browser.min.js raw 108,690 B (108.7 KB / 0.109 MB), gzip 31,875 B (31.9 KB / 0.032 MB), br 28,013 B (28.0 KB / 0.028 MB); delta raw -152,313 B (-152.3 KB / -0.152 MB), gzip -17,924 B (-17.9 KB / -0.018 MB), br -13,071 B (-13.1 KB / -0.013 MB).
