Thinking Levels (/think directives)

What it does

Inline directive in any inbound body: /t <level>, /think:<level>, or /thinking <level>.
Levels (aliases): off | minimal | low | medium | high
- minimal → “think”
- low → “think hard”
- medium → “think harder”
- high → “ultrathink” (max budget)
- highest, max map to high.

Send a message that is only the directive (whitespace allowed), e.g. /think:medium or /t high.
That sticks for the current session (per-sender by default); cleared by /think:off or session idle reset.
Confirmation reply is sent (Thinking level set to high. / Thinking disabled.). If the level is invalid (e.g. /thinking big), the command is rejected with a hint and the session state is left unchanged.

Pi/Tau: injects --thinking <level> (skipped for off). Other agent paths have been removed.

Levels: on|full or off (default).
Directive-only message toggles session verbose and replies Verbose logging enabled. / Verbose logging disabled.; invalid levels return a hint without changing state.
Inline directive affects only that message; session/global defaults apply otherwise.
When verbose is on, agents that emit structured tool results (Pi/Tau, other JSON agents) send each tool result back as its own metadata-only message, prefixed with [🛠️ <tool-name> <arg>] when available (path/command); the tool output itself is not forwarded.

Heartbeat probe body is HEARTBEAT /think:high, so it always asks for max thinking on the probe. Inline directive wins; session/global defaults are used only when no directive is present.

The web chat thinking selector mirrors the session's stored level from the inbound session store/config when the page loads.
Picking another level applies only to the next message (thinkingOnce); after sending, the selector snaps back to the stored session level.
To change the session default, send a /think:<level> directive (as before); the selector will reflect it after the next reload.
