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.

+The server came up clean. After four months. The whole cluster, all sixteen nodes, finally passing the long-running stress test that had been failing in one subtle way or another since January. He stood up from his chair. Walked to the doorway of his office. Looked up and down the empty hallway — everyone else gone for the night. Came back and read the green PASS lines one more time. Then he closed the laptop lid. Softly. And stood there with his hands on the edge of the desk, head down, grinning at the floor, because there was no one to high-five and he had earned every high-five he was not going to get.
