Removes the ekko / hermes-web-ui branding from the whole tree and drops eight locale files, so the project presents one name and one language pair. Data compatibility is deliberate, not accidental: DB filenames, the JWT audience, and skill manifest ownership all still recognise their pre-rename values so existing deployments under ~/.hermes-web-ui keep working without a re-login or a re-injection. scripts/harness-check.mjs now scans for the legacy strings and fails the build on any new occurrence, with an explicit allow-list (and reasons) for the compatibility paths that must keep them.
