feat(runtime): survival-bot pivot — MC chat is dialog-only (Phase 0) (#12)
Phase 0 of plans/autonomous-survival-bot-prd.md: change the product direction from operator-driven remote control to autonomous survival resident. MC chat is dialog-only for everyone, including OPERATOR_USERNAMES — commands like come/follow/build/pause/stop are recorded in the diary but not dispatched. TUI remains the only local control plane. Runtime changes: - Remove operatorGoalReflex from reflex.js (the come-here chat command). - Replace handleOperatorChat in bot.js with a dialog-only handleChat that answers greetings/status questions and records command-like verbs (en+ru) without dispatching them. - Default MC_VERSION to "auto" in runtime/config.js; mineflayer receives `false` to trigger version auto-detection. - Update auto-escalation prompt's reflex chain summary. Docs: - AGENTS.md: product pivot notice up top; chat-driven scope-trust is flagged as legacy/Pi-only. - README.md / docs/runtime.md: replace operator-chat command list with dialog-only description; update reflex chain summary. - docs/roadmap.md: Phase 2/3 marked superseded by the PRD where they assumed chat-driven control.

## Operator chat commands

## In-game chat (dialog-only)

Players listed in `OPERATOR_USERNAMES` can address the bot in MC chat
|
||||
by prefixing the message with the bot's name:
|
||||
As of the Phase 0 survival-bot pivot, MC chat does **not** drive bot
|
||||
actions for anyone, including names listed in `OPERATOR_USERNAMES`.
|
||||
The bot will:
|
||||
|
||||
```
|
||||
pepa_bot status → bot replies with HP / food / pos / hostiles / busy
|
||||
pepa_bot come → bot pathfinds to the operator's current position
|
||||
pepa_bot pause → reflex loop stops
|
||||
pepa_bot resume → reflex loop resumes
|
||||
pepa_bot stop → graceful disconnect + process exit
|
||||
```
|
||||
- reply to greetings (`hi`, `привет`, etc.) and to being addressed by
|
||||
name, rate-limited;
|
||||
- answer status questions (`pepa_bot status`, `как дела`, `what are
|
||||
you doing?`) from the live snapshot;
|
||||
- detect command-like verbs (`come`, `follow`, `build`, `pause`,
|
||||
`stop`, `give`, …) when addressed, record them in the diary, and
|
||||
reply once per cooldown that MC chat is dialog-only.
|
||||
|
||||
Unrecognized commands get a polite "didn't recognize" reply. Operator
|
||||
identity verification is the server's job (AuthMe on cracked,
|
||||
online-mode on premium) — the bot trusts the nickname.
|
||||
Local control of the bot (pause/resume/stop, sending chat manually,
|
||||
escalating to Pi) lives in the TUI. Long-term control (skills,
|
||||
runtime code, proposals) lives in the repo. `OPERATOR_USERNAMES` is
|
||||
still used to **label** speakers in logs (`operator <name>` vs
|
||||
`player <name>`), and remains the right place to plug a future
|
||||
trusted control channel (e.g. Telegram bridge).
