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 email was already half-written when the next meeting notification chimed. He skimmed the last few lines he'd typed, couldn't quite tell if they landed, hit send anyway. Opened the meeting. Half-listened while triaging the inbox with the other half of his attention. A colleague asked him a question and he answered too quickly and only later realized he'd answered the wrong question entirely. At 4pm, walking to the coffee machine, he realized he couldn't name a single thing he had actually completed that day. Everything had been touched. Nothing had been done. His shoulders were up somewhere near his ears.
