Stack PR 1/7 — base: accelerator

Adds the AcceleratorDaemon subprocess wrapper that spawns the Go accelerator binary on a Unix domain socket, mints a per-daemon stdin handshake secret, waits for the UDS to become connectable, and manages teardown.


Accelerator stack

  1. daemon subprocess wrapper ← this PR
  2. route read_row and mutate_row through daemon
  3. forward auth/identity config to daemon
  4. verify daemon identity before routing
  5. authenticate RPCs with stdin handshake secret
  6. pass Python client version for User-Agent
  7. package prebuilt daemon into wheel
