Reproduce the missing `#repo:` route with a real isolated Codex TUI, extend
input observation to recognize enhanced terminal Enter encodings without
rewriting pane input, add regression and real-Codex smoke evidence, install the
fix, and update the operator documentation.

## Completion evidence

- Reproduced the failure with two isolated real Codex 0.149.1 panes: Codex
  submitted the source line but no durable message was created.
- Raw input capture showed CSI cursor/device replies preceding the typed route;
  these contaminated the tap's observation buffer before the terminating CR.
- The observer now removes terminal protocol sequences and applies local
  backspace editing only to its parsing copy while forwarding source bytes
  unchanged.
- A network-disabled two-Codex rerun created one durable `#audit-core:` message,
  transitioned it to `injected`, and showed the `# from flex-auth:` prompt in
  the target's queued follow-up inputs.
- Full checks and installed-package verification passed. No user session or
  durable user message was changed during diagnosis.
