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.

+- `U+E90A` — Hermes, traced from the Hermes app icon (<https://hermes-agent.nousresearch.com/>), the same art the `hermes-desktop` package ships as its icon
 
 The agent marks are monochrome so the menu can render them using the active
 theme's foreground and selection colors.
