v0.1.0 — First public open-source release

[0.1.0] - 2026-07-16

First public open-source release. Ships full multi-language support, a
professional codebase pass, and repository hygiene for outside contributors.

Added

• Multi-language UI across five locales — Indonesian, English, Spanish,
  Chinese, and Arabic — including full right-to-left (RTL) layout support.
• Mobile-reachable language switcher inside the user menu, so locale can be
  changed without a desktop-only control.
• Complete i18n coverage down to the last-mile data and logic strings (100%).

Changed

• Global app header is now cleanly separated from the per-feature header,
  fixing an obscured mobile language switcher along the way.
• Editor and Full Preview tabs are now desktop-only, reflecting where each view
  is actually usable.
• Codebase professionalized for open source: refreshed docs, an .env.example,
  and a consistent Conventional Commits history.

Removed

• Roughly 420 lines of dead code and one dependency removed in a repo-wide
  cleanup audit — deduplicated hooks and helpers, merged duplicate logic, and
  a leaner tsconfig/auth surface — with no user-visible behavior change.
