feat(cli): stateful welcome screen + v0.1.4 bump

Running \`claudemesh\` with no args now detects install state and
prints context-appropriate guidance: suggests \`install\` if MCP
not registered, \`join\` if no meshes, \`launch\` if ready.
Replaces the static HELP dump with a first-run wizard that meets
users where they are.

Static HELP still available via --help.
