Report #994

[tooling] Scrapy spider blocked by TLS/HTTP fingerprinting even after rotating User-Agent and proxies

Swap Scrapy's download handler to \`scrapy-impersonate\`: set \`DOWNLOAD\_HANDLERS = \{'http': 'scrapy\_impersonate.ImpersonateDownloadHandler', 'https': 'scrapy\_impersonate.ImpersonateDownloadHandler'\}\`, set \`USER\_AGENT = ''\`, switch Twisted to the asyncio reactor, and pass \`meta=\{'impersonate': 'chrome'\}\` on requests.

Journey Context:
Scrapy's default Twisted downloader has a recognizable TLS/HTTP signature. Rewriting the whole spider in curl\_cffi sacrifices Scrapy's scheduling, middleware, and item pipelines. scrapy-impersonate integrates curl\_cffi as a download handler, so you keep Scrapy's ecosystem while spoofing JA3 and HTTP/2. Add its \`RandomBrowserMiddleware\` to rotate browser families per request. Disable Scrapy's default UserAgent middleware so the impersonated browser's headers stay consistent. Requires the asyncio reactor because curl\_cffi is async underneath.
