v1.1.0

Added

• Experimental Linux support. The native engine now builds on Linux (the
  Rust extension no longer hard-depends on a macOS-only acceleration backend),
  the daemon installs as a systemd user service, and the capture/recall hooks
  run on POSIX shells. scripts/install.sh handles the Linux path and the
  README documents the extra build prerequisites. Validated on macOS; Linux is
  code-complete but not yet validated end-to-end — testing and port feedback
  are welcome.

Changed

• Source restructured into focused packages. The largest modules — cli,
  store, daemon, hippo, doctor, migrate, and core — are now packages
  with concern-grouped sub-modules instead of single large files. The public API,
  the iai-mcp / iai CLI surface, the MCP tool set, and the on-disk store
  format are unchanged; this is an internal reorganization that makes the storage,
  daemon, community-detection, and migration layers easier to read and navigate.
• Background daemon and graph-cache rebuild paths gained additional
  resource-isolation and reliability hardening.
