v0.11.0

Optimising compiler — roadmap §4.3 (Bytes-ids, the id half).

Added

• W040 — stringified-id warning. The checker now flags an entity keyed on a
  single Bytes/Address value stringified with .toHexString() / .toHex()
  (directly, or via a local), and recommends id: Id<Bytes>. A Bytes id (with
  immutability) indexes ~28% faster and stores ~48% less than the equivalent
  hex-string id (Edge & Node benchmark). Genuine composite keys
  (a.toHexString() + "-" + b…) and literal-string ids are never flagged.
  This is a warning rather than an auto-rewrite: converting a String id to Bytes
  changes the stored id representation (hex-string → raw bytes), so it is a data
  change the author opts into — unlike immutability inference, which is
  store-identical. Registered in redstart explain W040. Brings the diagnostic
  catalogue to 31 codes (26 errors, 5 warnings).
