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.
