Simplify the docs and stabilize Qwen replay output

[bigboateng]

Change contract

When: A developer starts using Pitot or looks up host setup and control boundaries.
Before: The README combines a long setup reference with images, and some examples overstate runtime telemetry or omit source-build pin limits. The Qwen CI fixture can select a pipe-output path that resolves before all output is collected.
After: A short, plain README links dedicated host, runtime and protocol references, prioritizes Codex, Qwen and DeepSeek, and introduces the offline supervisory-control example. The Qwen test fixture uses its supported terminal mode and rejects pipe fallback before its canary executes.

Boundaries preserved

• All eleven documented hosts and the existing native macOS/Linux/Windows CI matrix remain covered.
• Runtime control remains limited to supported actions; documentation explicitly states shell, trust, privacy and failure boundaries.
• Qwen configuration changes are confined to the isolated CI fixture. Agent versions, product behavior and the full allow/deny evidence gate remain unchanged.
• Incomplete runs expose bounded receipt counts; malformed or oversized receipts report unavailable without exposing their contents.

Evidence

Scenario or check	Expected result	Observed result
Actual Qwen terminal and pipe probes on macOS	Terminal returns nonce-bound result; pipe is rejected before execution receipt	10 terminal passes and 10 pipe rejections
Canary, protocol and receipt regression tests	Reject fallback and malformed diagnostics; preserve correlated native results	Focused checks pass
Formatting, static analysis and full maintenance suite	Clean generated and source checks	Pass; 236 maintenance tests, 3 platform-specific skips
Native authenticated capture	Complete current evidence across all three operating systems	All 33 native cells passed
Final PR CI	Exact-head checks and current agent/runtime report	49 checks passed; 33 agent and 3 runtime cells pass

Failure and recovery

A missing terminal or incomplete agent trajectory still fails CI. Revert fixture changes and regenerate their authenticated capture together if recovery is needed.

Remaining limits

The earlier Linux failure's exact process event ordering was not retained. A synthetic event sequence demonstrates the pipe-output loss mechanism; local native probes did not reproduce that original failure. Finite replay tests do not establish universal host behavior or live provider availability. The supervisory replay example remains documented for macOS/Linux.
