Polish ten-moss README (#458)

Rewrites apps/ten-moss/README.md for a cleaner, more professional read.

- Replaces the ASCII pipeline diagram with two GitHub-native Mermaid
diagrams (architecture flowchart and per-turn sequence diagram), both
verified to render.
- Adds a stack-at-a-glance table and converts the Moss delta,
latency-breakdown fields, simulate-remote values, and configuration into
proper tables. Config defaults are sourced from property.json and
MossSessionConfig (including the previously undocumented
moss_max_context_chars).
- Tightens section structure and wording; no technical content changed.
