Add Periscope (pscp.tv) extraction test and broadcasts_count field

[Copilot]

Periscope scheme existed but had no tests and was missing broadcast count extraction.

• schemes.py: Added broadcasts_count field extracting n_broadcasts from user profile data
• test_socid_improvements.py: Added unit test with mock HTML fixture covering all 16 extracted fields (identity, social counts, verification flags, Twitter linkage, emoji display name)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.pscp.tv
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
