Jason Tudisco 17d68dbb75 feat(kez-chat/web): real zstd compact form + 3-way format toggle on AddClaim
- Add @bokuweb/zstd-wasm; replace the kez:zd1: deflate-raw placeholder
  with spec-compliant kez:z1: zstd(JSON envelope) compact form.
- Dynamic import keeps the WASM (~348 KB) in its own Vite chunk so the
  initial bundle only grows from 113 KB to 116 KB; the WASM is fetched
  the first time a user picks compact format.
- AddClaim.svelte: 3-way format toggle (compact / markdown / JSON).
  DNS defaults to compact since TXT records want the shortest payload.
- Drop the v0.1 apology in DNS instructions — kez:z1: is the spec form
  and verifiers can decompress it directly.
- Cross-impl interop verified: browser-generated kez:z1: decompresses
  cleanly in the Rust CLI and the Node port, byte-for-byte modulo
  JSON key-order whitespace.
