v1.1.1

Fixed

• Linux runtime fixes for the experimental Linux path: daemon binder detection
  gains an ss fallback, ANN query distances are clamped to a valid range, and
  the multiprocess store path no longer races on table visibility. Linux remains
  experimental and unvalidated end-to-end — testing and port feedback are welcome.

Changed

• Internal cleanup only — no changes to the public API, the iai-mcp / iai
  CLI, the MCP tool set, or the on-disk store format: the sleep-pipeline
  compatibility shim was removed in favour of the canonical module, sleep-step
  names were made consistent, and more wall-clock benches are gated out of the
  default test run.
