MAESTRO: Merge PRs #920 and #699 - Add project exclusion and folder CLAUDE.md exclusion settings

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.
