Update rustlabs

[FaiThiX]

Summary

This PR improves the external RustLabs refresh workflow and keeps it fully decoupled from runtime bot data.

RustLabs.js remains unchanged and still reads from src/staticFiles.
The refresh script now writes only intermediate output to src/external/rustlabs for manual post-processing.

Motivation

Refreshing RustLabs data became unreliable due to Cloudflare protection and recent markup changes (Blueprint/Mixing/Durability pages).
This PR makes refreshes more robust and prevents commit noise from generated files.

What Changed

• Changed external refresh output target to src/external/rustlabs.
• Added ignore rules for generated external refresh output.
• Improved request diagnostics for HTTP/proxy/timeout/DNS failures.
• Added Cloudflare session support via environment variables:
  • RPP_RUSTLABS_CF_CLEARANCE
  • RPP_RUSTLABS_COOKIE
• Added proxy behavior controls:
  • default: ignore proxy
  • opt-in: RPP_RUSTLABS_USE_PROXY=true
• Ensured JSON files are written only after a successful full run (no partial snapshots).
• Hardened parsing against current RustClash structure changes:
  • Blueprint tab parsing improvements
  • Research type handling for iotable (Engineering Workbench, 210787554)
  • Durability row/quantity parsing tolerance improvements
  • Craft parsing now supports mixing tabs (teas, etc.)
  • Mixing/Crafting workbench recognition includes:
    • Mixing Table (1259919256)
    • Cooking Workbench (1456143403)
• Moved playwright-core to devDependencies (not required for normal bot runtime installs).

Non-Goals

• No automatic import from src/external/rustlabs into src/staticFiles.
• No behavior change in RustLabs.js runtime loading.

Validation

• Refresh without cookie now fails with explicit Cloudflare hints instead of a generic fetch error.
• Refresh with a valid session can proceed and generate all rustlabs*.json under src/external/rustlabs.
• Blueprint/Mixing data paths are parsed correctly for affected items (teas/pies/workbench variants).
• Bot runtime remains unaffected because src/staticFiles and RustLabs.js are unchanged.

Notes for Reviewers

.

• This script is an external maintenance tool and is intentionally separated from bot runtime data flow.
