Conflicts: - `app/validators/status_length_validator.rb`: Upstream changes too close to glitch-soc MAX_CHARS changes, but not a real conflict. Applied upstream changes. - `package.json`: glitch-soc-only dependency textually too close to a dependency updated upstream, not a real conflict. Applied upstream changes.
