kitty: color terminal tabs by ssh/mosh host
Tint the kitty tab background by target host so local vs remote (and which remote) is visible at a glance. - __kitty_host_color: explicit color table for known hosts (routers, resolvers, ryzen/mini, personal cloud, geo VPS) + stable hashed palette fallback; auto-picks readable fg by luminance - __kitty_ssh_host: parse target host from ssh/mosh-style argv - __kitty_tab_set/__kitty_tab_reset: active tab = full host-color bg, inactive tab = dark theme bg with host-color text; revert on exit - ssh wrapper + s (kitten ssh) and m (mosh) wired to tint/reset Also includes unrelated pending dotfile changes (GH MCP PAT from keychain in fish/zsh, kitty/wezterm font_size 15->14, kitty colorspace displayp3) committed together at user request.
