Simplified Permission System / Claude Code v2.0.35

What: Migrated ignorePatterns configuration to unified permissions system.

Details:

The ignorePatterns field is automatically migrated to permission rules on first run
After successful migration, ignorePatterns is removed from config file
Runtime file access checking now uses unified xC() permission function instead of separate GN() ignore checker
Behavior remains the same - patterns still block file access, just through the permissions infrastructure
Evidence: u6A() at line 474347 (simplified from IsA()), se2() at line 487463 (migration with cleanup at line 487480)

Anthropic's note

Upstream's own release notes for v2.0.35 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.

Migrated ignorePatterns from project config to deny permissions in the localSettings.

Is this right?
