Adds a skin system that lets users customize the CLI's visual appearance through data files (YAML) rather than code changes. Skins define: color palette, spinner faces/verbs/wings, branding text, and tool output prefix. New files: - hermes_cli/skin_engine.py — SkinConfig dataclass, built-in skins (default, ares, mono, slate), YAML loader for user skins from ~/.hermes/skins/, skin management API - tests/hermes_cli/test_skin_engine.py — 26 tests covering config, built-in skins, user YAML skins, display integration Modified files: - agent/display.py — skin-aware spinner wings, faces, verbs, tool prefix - hermes_cli/banner.py — skin-aware banner colors (title, border, accent, dim, text, session) via _skin_color()/_skin_branding() helpers - cli.py — /skin command handler, skin init from config, skin-aware response box label and welcome message - hermes_cli/config.py — add display.skin default - hermes_cli/commands.py — add /skin to slash commands Built-in skins: - default: classic Hermes gold/kawaii - ares: crimson/bronze war-god theme (from community PRs #579/#725) - mono: clean grayscale - slate: cool blue developer theme User skins: drop a YAML file in ~/.hermes/skins/ with name, colors, spinner, branding, and tool_prefix fields. Missing values inherit from the default skin.
