docs: add agent quickstart guides for all SDK languages

[ericciarla]

Summary

• Add canonical agent quickstart docs for Node.js, Python, Rust, Java, and Elixir in agent-quickstart/
• Each file covers search, scrape, and interact endpoints with complete parameter tables
• Generated from SDK source code and the v2 OpenAPI spec — not from existing docs
• Every parameter is confirmed from source; no invented methods, defaults, or behavior

What's in each quickstart

• Install command
• Auth pattern
• "When To Use What" decision guide
• For each of search/scrape/interact: why to use it, preferred SDK method, realistic example, full parameter table with types and descriptions
• Language-specific notes (naming conventions, deprecated aliases, SDK quirks)
• Source of truth file listing

SDK versions covered

Language	Package	Version
Node.js	firecrawl	4.35.0
Python	firecrawl-py	latest v2
Rust	firecrawl	2.16.0
Java	firecrawl-java	1.15.0
Elixir	:firecrawl	1.9.2

Language-specific differences documented

• Java SDK: interact supports code only (no prompt parameter)
• Elixir SDK: interact supports code only (no prompt parameter); function names are OpenAPI-generated
• Python SDK: snake_case params, prompt is keyword-only on interact
• Rust SDK: dedicated options structs for JSON, screenshot, change tracking formats

Test plan

• Verify each .mdx file renders cleanly in Mintlify
• Cross-check parameter lists against latest SDK releases
• Confirm no localized files were modified
