Add a model-visible skills block to the system prompt (progressive
disclosure: lists name/description/path, never inlines SKILL.md bodies)
with a 12k-char prompt budget and a 512-char per-description cap.
EngineConfig gains skills_dir, threaded through the three construction
sites (TUI app, exec agent, runtime thread manager).
README skills section is rewritten to document the discovery order,
the SKILL.md frontmatter contract, and the install/update/uninstall/
trust commands. Adds Simplified Chinese README cross-link and full
README.zh-CN.md translation (DeepSeek went viral in CN -- discoverability
matters).
Tests cover happy path, empty/missing dir → None, oversize description
truncation with U+2026 marker, internal-whitespace collapse, and the
overflow-budget omission notice.
