Feat(templates): add lead-scraper python template

[arthursita-plank]

Note

Medium Risk
Mostly additive template code, but it introduces new API-driven browser automation and replay recording behavior that could fail at runtime or incur cost if used incorrectly.

Overview
Adds a new Python lead-scraper app template that uses Anthropic Computer Use with Kernel’s Computer Controls API to navigate arbitrary sites from a URL + natural-language instructions and return extracted leads.

The template includes an action (scrape-leads) with validated inputs/outputs, JSON parsing + dynamic CSV generation, an async Kernel browser session manager with optional replay recording, and a port of Anthropic’s tool/sampling loop wired to Kernel mouse/keyboard/screenshot primitives. Documentation is updated to expose the new template and provide setup/invocation examples (including .env.example).
