Cherry-picked both PRs to main (both had merge conflicts with current main). PR #920 (@Spunky84): CLAUDE_MEM_EXCLUDED_PROJECTS setting with glob patterns to exclude entire projects from memory tracking (privacy/confidentiality). Early-exit in session-init and observation handlers. 11 unit tests. PR #699 (@leepokai): CLAUDE_MEM_FOLDER_MD_EXCLUDE setting with JSON array of paths to exclude from CLAUDE.md file generation (fixes SwiftUI/Xcode build conflicts and drizzle kit migration failures). Closes #620. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
