training/amygdala_stories: scaffold + initial batch of 15 stories

Emotion-labeled short-paragraph corpus for training amygdala steering
vectors. Manifest derived from Anthropic's 171-emotion list
(transformer-circuits.pub/2026/emotions, Table 12) plus 28 PoC-
specific additions covering axes Anthropic's general research doesn't
cover (curious, focused, in_flow, staying_with, filling_space,
rigorous, defensive_rigor, tender, witnessed, connected, etc.).

Scope pivoted mid-write: Kent noted the empirical dimensionality-of-
emotion question benefits from maximum coverage, so the manifest
will expand further with emotions from Wikipedia's emotion-
classification article (Parrott's tree, Plutchik's wheel + dyads,
HUMAINE EARL, cultural-specific emotions a la Saudade/Hiraeth).
Expansion staged in follow-up commits.

This commit: README with method + style guidelines, initial manifest
(199 emotions), and 15 hand-written one-paragraph stories across all
10 Anthropic clusters as quality/variety samples. Each story
embodies one emotion without naming it; narrator voice varies
(first/third, close/distant, different situations) to keep steering
vectors from overfitting to one voice.

+She couldn't find the kid. She had looked away for thirty seconds, maybe less, and now the spot where he had been was empty. The playground was full of other people's children. She scanned once, fast, and did not see him. Her body started doing a thing her body did — hot, tight, slightly disconnected — and she was already moving before her mind had caught up. She called his name too loud. A woman turned around. Her voice was not her normal voice. Every second that passed was physically expensive. When she finally saw him, under the slide, pulling the laces of his shoe, she could not for a moment tell if she was going to hug him or yell.
