Add agent quickstart docs for all SDK languages

[ericciarla]

Summary

• Adds one canonical agent quickstart file per SDK language in agent-quickstart/: Node.js, Python, Rust, Java, and Elixir
• Each file covers the three core endpoints: search, scrape, and interact
• Every file includes: install instructions, auth patterns, "when to use what" guide, preferred SDK method names, working examples, complete parameter tables with descriptions and defaults, deprecated alias migration notes, and language-specific caveats
• All content sourced from SDK source code (primary) and the OpenAPI spec (secondary) — no invented parameters or defaults

Details

Each quickstart follows a consistent structure:

1. Install / Authenticate
2. When To Use What (search vs scrape vs interact)
3. Per-endpoint sections with why, method name, example, and full parameter table
4. Notes on language-specific conventions (naming, patterns, deprecated aliases)
5. Source of truth references

Language-specific highlights:

• Node.js: Documents Zod schema integration for type-safe JSON extraction, camelCase conventions
• Python: Documents snake_case parameter naming, SearchData migration (.web/.news/.images instead of .data)
• Rust: Documents struct update syntax with Default, impl AsRef<str> ergonomics, async/Tokio requirement
• Java: Documents builder pattern, method overloading for defaults, CompletableFuture async variants
• Elixir: Documents auto-generated OpenAPI function names, keyword list params, atom enum values, bang variants

Notable cross-language differences documented:

• prompt parameter for interact is available in Node.js, Python, and Rust but not in Java or Elixir
• Search limit default varies: 5 (Python), 10 (OpenAPI/Node.js/Java), 20 max (Rust)
• Elixir function names follow OpenAPI operation IDs (scrape_and_extract_from_url vs scrape)

Test plan

• Verify each .mdx file renders cleanly as a Mintlify docs page
• Confirm parameter tables match current SDK source
• Check code examples for syntax correctness
• Validate frontmatter fields
