Lead with agent development and switch the website to light

[asim]

The README starts with an RPC greeter and buries the conversational development experience. The website also hard-codes dark sections even independently of the theme toggle.

This change leads with micro chat, generating services the agent can use as tools, and a complete Go agent setup. It distinguishes CLI service generation from named agents, moves the service walkthrough below agents, simplifies the CLI section, and repairs README links.

The website uses light backgrounds throughout the homepage, support page, navigation, and footer. Cards, text, buttons, and code colors are adjusted for light surfaces; automatic dark mode is disabled. The design notes reflect the new theme.

Validation:

• go build ./... passed.
• New README agent snippet compiled against this checkout.
• golangci-lint run ./... passed (0 issues).
• README relative links and git diff --check passed.
• Full go test ./... was blocked by automatic approval review when tests attempted to contact Atlas Cloud; it was not rerun.
• Hugo production build passed: 1,828 pages. Local PostCSS resolution used NODE_PATH=$PWD/node_modules; existing Docsy deprecation/sidebar warnings remain.
• Browser theme checks passed at 1440px and 390px on the homepage, getting-started docs, blog, and support page: light body/header/footer, no dark toggle, and no horizontal overflow even with a dark system preference and saved dark theme. Homepage and support screenshots reviewed. External CDN assets were blocked during local visual checks.
• Follow-up adjustment keeps footer links readable on the light background.
