herdr-lead: one-time install

One-time install, from the skill's real directory (readlink ~/.claude/skills/herdr-lead, currently ~/dev/skills/agent/herdr-lead), not the symlink:

pnpm install --dir plugin                       # pi-tui; the board will not start without it
chmod +x plugin/cli.ts && ln -sfn "$PWD/plugin/cli.ts" ~/.local/bin/herdr-lead
herdr plugin link "$PWD/plugin"                 # registers the open/focus actions

Linking registers the action but binds no key. Add one to config.toml — and note prefix+shift+l ships as swap_pane_right, so it must be moved or the custom command is silently disabled (herdr keeps the built-in on a conflict):

[keys]
swap_pane_right = "prefix+>"    # same physical key, spelled as the shifted char

[[keys.command]]
key = "prefix+shift+l"
type = "plugin_action"
command = "herd-lead.focus"
description = "jump to / from herd lead board"

Spell shifted punctuation as the shifted character (prefix+>), never prefix+shift+. — the latter parses but never fires, since the terminal sends > and the matcher only bridges the two when the config names the shifted char. herdr config check reports conflicts and unparseable keys; herdr server reload-config prints the diagnostics that a silent disable would otherwise hide.

Symlinking the skill into ~/.claude/skills/herdr-lead is what makes both /herdr-lead and the ~/.claude/skills/... paths below resolve — the plugin works without it, the skill does not. After moving the plugin or editing the keybinding, run herdr server reload-config — herdr reads config.toml once at startup, so a stale path makes the keybinding fail silently.
