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.

+Richard let them finish arguing before he spoke, which was a move he'd been developing for a few years. He waited until the meeting had tangled itself completely and the director was rubbing her eyes. Then he said the thing he'd been sitting on for twenty minutes, the thing that solved it in one sentence, and he said it slowly. He watched a couple of faces rearrange themselves. He didn't quite smile. He let them come around to thanking him. When Ben said "nice catch" Richard said "oh, I just thought I'd mention it" in a tone that meant he had known, of course he had known, and he picked up his coffee and sipped it.
