Add typedoc and typedoc-plugin-markdown as devDependencies. Add typedoc.json config
targeting src/index.ts with markdown output to .github/wiki/api. Add docs script to
package.json. Generate initial API reference pages.
Part of T-E8-03 — TypeDoc automation for all 12 JS/TS packages.
- Extract magic numbers into named constants (DHUHR_OFFSET_MINUTES,
ANGLE_MIN/MAX, LAT_SCALE) with source citations for MCW coefficients
- Add input validation (RangeError) for lat, lng, tz, elevation on all
public API functions (getTimes, getTimesAll)
- Optimize solar ephemeris: computeAngles() returns declination so
getTimes/getTimesAll reuse it for Asr instead of computing twice
- DRY: shared constants.ts for DEG, Dhuhr offset, angle bounds
- Improve MethodEntry type with labeled tuple elements and NaN docs
- Add stricter tsconfig (noImplicitReturns, noFallthroughCasesInSwitch)
- Switch tests to node:test framework (TAP output, describe/it blocks)
- Add 8 new input validation tests (104 ESM + 13 CJS total)
- Add ESLint + Prettier with CI lint job
- Remove src/ from npm package files (smaller published tarball)
- Document NaN return behavior in JSDoc for getTimes/getTimesAll
