Task 081: Rustdoc ビルド・デプロイ

Status: DONE

Motivation

Human directive: 「rustdoc などもビルドしてデプロイに含めること」

Implementation

• build.ts: Copies target/doc/ to dist/doc/ via recursive directory copy
• pages.yml: Added cargo doc --no-deps --document-private-items step
• templates.ts: Added "API Docs" link in site footer
• Fixed rustdoc warnings in propagation.rs (escaped [x,y,z] in doc comments)

Output

• dist/doc/solar_line_core/ — Core crate API docs (orbits, propagation, ephemeris, etc.)
• dist/doc/solar_line_wasm/ — WASM bridge API docs
• Accessible from site footer "API Docs" link

Test Results

• 970 TS tests, 177 Rust tests passing
• Site builds with rustdoc: "Built: ... + rustdoc → dist/"
