Add Hermes as a desktop app and a coding agent

Hermes joins Install > AI as a desktop app, sits beside it under Remove > AI, and becomes a choice in the default-agent list. The CLI installs through omarchy-install-hermes-cli rather than a bare `mise use`, so its interpreter is pinned before mise builds it. Rebased onto quattro. Ori claimed U+E909 in #7709 while this branch was open, so the Hermes mark moves to U+E90A in the icon font, the menu entries, the font README, and the charset the menu test pins. The glyph outline itself is unchanged; it is spliced in beside Ori rather than over it.
