Expand guided reflection with CBT thought record and distortion routing

Adds a 5-step negative-mood reflection flow with an evidence-examination
step, Socratic templated questions that back-reference prior answers, and
a deterministic cognitive-distortion detector that routes the perspective-
check prompt to a distortion-specific reframe. Includes CBT plan docs,
flowchart, stats research notes, and MCP config.
