v0.9.0 — claims gate status, file read, test run

[0.9.0] — 2026-07-01

Added

• simplicio-dev-cli claims gate status — explicit claims-gate command exposing
  the MEASURED/CANON/UNVERIFIED discipline as a first-class CLI surface, plus a
  resilient inspect status path that degrades gracefully when the compiled
  runtime is unavailable.
• simplicio-dev-cli file read — read raw file contents with optional
  line-range slicing, delegating to the native Rust simplicio file read
  binary when available (via simplicio.runtime_bridge) and falling back to a
  pure-Python implementation otherwise.
• simplicio-dev-cli test run — run the project's test suite through the CLI,
  mirroring the Rust CLI contract for consistent output between the compiled
  runtime and the Python fallback.

Changed

• Documented the runtime-first execution chain: simplicio-runtime owns
  task/run/gate/evidence orchestration, simplicio-dev-cli remains the focused
  development/test executor, and decided mechanical writes should flow through
  simplicio edit when the compiled runtime is available.
• Added simplicio-dev-cli edit as a runtime-aware alias: it delegates to the
  compiled simplicio edit when available and falls back to the existing Python
  mechanical-edit executor when the runtime is absent or explicitly disabled.
