feat: local strata analysis with prose + arrows, no container
Strata analysis now runs on cloudy (local machine) via
scripts/strata-analyze.py, not in a Cloudflare Container. The script
fetches islands from the API, asks letta to produce structured prose
with semantic arrows (→, ←, ↔, ⇏), then uploads the results to
Cloudflare via PUT /api/strata/islands/:id/analysis.
The strata page renders prose with styled arrows showing relationships
between vertices — no canvas graph. Island cards link directly to the
strata page and show "View Strata" when analysis exists.
- Removed: AnalysisContainer durable object, container analysis endpoint,
CarryGraph class, apiPost helper, POST /api/strata/analyze
- Added: PUT /api/strata/islands/:id/analysis endpoint, strata column
in island_cache, scripts/strata-analyze.py, D1 migration
- Frontend: strata page shows prose with arrows, themes, tensions,
open questions, synthesis
