Documentation out, and a version that says it is finished

The working notes, the roadmap, the glossary and the review notes are on the
wiki; README points there. assets/Translation.xml stays -- it is the mod.

1.0.0: both the base game and Echoes of the Eye are translated, which was the
whole goal. manifest.json said 0.1.0 because nothing had ever changed it.

+## Unreleased
+
+## 1.0.0 — 2026-08-08
+
+The first tagged version: *Outer Wilds* and *Echoes of the Eye* are translated,
+which is what this mod set out to do.
+
+### Added
+
+- Slovak localization of *Outer Wilds* and *Echoes of the Eye*, as an OWML mod
+  built on `xen.LocalizationUtility`.
+- A fixed glossary of proper nouns and recurring terms, so names stay consistent
+  across the whole script.
+
+### Changed
+
+- The documentation left the repository. The working notes, the phase roadmap,
+  the glossary and the in-game review notes are now the
+  [wiki](https://git.houmeres.sk/Houmeres/Outer-Wilds-SK-Translation-Mod/wiki),
+  and the history was rewritten in the same pass so they are not present at any
+  commit. `assets/Translation.xml` stays here — it ships with the mod.
+
+### Note on history
+
+Any clone taken before 2026-08-08 has a different history and should be
+discarded rather than merged.
