zhanghui 25964ccbb3 fix(observability): don't spawn a root trace per cascade embedding 
The embedding-observation change wrapped every _embed_chunk call in a
span. Cascade-time indexing embeds run outside any request trace, so each
chunk started its OWN root trace — a per-chunk trace explosion (13 orphan
everos.embedding traces per add/flush), detached from session/user and
contrary to the "cascade is not instrumented" decision.

memory_span gains nested_only: open a span only when one is already
active. Embedding uses it, so search/flush embeds still nest under their
recall/extract span, while cascade embeds no-op (no trace) — restoring the
cascade-untraced boundary.

everos package

Source layout for the everos Python package. This README is a quick orientation; full architectural detail lives elsewhere.

├── service/        Application: use case orchestration
├── memory/         Domain: extract + search + cascade + prompt_slots + models

Each subpackage has a top-level __init__.py describing its responsibility and public API.

Single-direction; enforced by import-linter in CI.
