fix: emit spec-compliant ESM with explicit .js import specifiers

- Add .js extensions to all relative imports in src/ and __tests__/.
- Switch module/moduleResolution to "nodenext" to enforce it.
- Add jest moduleNameMapper for .js -> source resolution.
- Bump 1.21.0 -> 1.21.1; update CHANGELOG and README (ESM/SSR).

feat: add getWeekendDays() and make package ESM-only
