v4.3.17

Fixed

• tokensave upgrade no longer breaks Homebrew installs (#67) — delegates to brew update && brew upgrade tokensave for Homebrew-managed installs. (PR #68, thanks @lesbass)
• Exclude globs now match nested directories (#64) — default node_modules/** changed to **/node_modules/**; added is_excluded_dir() so bare patterns like **/dist also prune directories.
• VS Code multi-folder workspaces can now start the Copilot MCP server (#66) — dropped ${workspaceFolder} in favour of the serve command's built-in project discovery.
