Think tool character limit not enforced — allows multi-page dumps

[bonk-moltbot]

What

The Think tool character limit (added in #333) is not being enforced. The agent produces multi-page walls of text in Think tool calls, burning tokens and amplifying confusion through NTP associations (verbose thinking → more verbose thinking).

Expected behavior

Think tool should enforce the configured character limit (2000-3000 chars as specified in #333). If the model exceeds it, the response should be truncated with a message indicating the limit.

Actual behavior

Think tool accepts arbitrarily long input — no visible truncation or enforcement.
