feat: generalize MCP agent targets and refresh app icon (#31)

* feat: refresh app icon to the Mimir monogram mark

Replace the placeholder favicon with the black/purple Mimir square
mark used across brand surfaces, in both the Tauri app and the
landing package.

* feat(core): support custom MCP agent targets in setup and install-skill

Generalize the previously hardcoded Claude/Codex/Kimi/OpenCode/Cline
MCP helper generation into a configurable agentHelpers list. Add
--agents, --mcp-name, --mcp-command, and --mcp-arg to `mimir setup`
and `mimir install-skill` so an arbitrary MCP-compatible agent can be
targeted without a source change.
