Improve CLI repository discoverability

[yosriady]

What changed

• add a standard MIT license for the public CLI and declare license: MIT in package.json
• document one-command installation of the public formo-analytics agent skill
• include an explicit global install example for Claude Code and Codex
• link the Agent Skills standard and the skill source from both README.md and SKILLS.md

The GitHub repository description, homepage, and discovery topics were also updated separately because they are repository settings rather than files.

Why

GitHub and package tooling could not detect a license, and users discovering the public skill did not have a canonical installation command. These changes improve trust, package metadata, and discoverability for CLI, MCP, and agent-skill users.

Validation

• pnpm build
• pnpm lint
• TEST_TOKEN=formo_test_placeholder pnpm test — 122 passing, 20 live integration tests skipped after the deliberately fake token received the expected 401
• npx -y skills add getformo/cli --list — discovers formo-analytics
• git diff --check
• destination links return HTTP 200
