Fix dependencies.sh: blank line, apt warning clarity, LLDB comment, xmake PATH guard

[Copilot]

Four minor but meaningful fixes to utils/dependencies.sh addressing readability, correctness, and user experience.

Changes

• Blank line removed — drop empty line between install_packages() declaration and case statement, consistent with rest of script
• Expanded apt-get update warning — failure message now tells the user installation will continue from cache and what to do if it ultimately fails:

  print_warn "Failed to update package list; continuing with installation using the existing package cache. If installation fails, please check your network connection or run 'sudo apt-get update' manually and re-run this script."

• LLDB comment on darwin — documents why the LLDB check only warns instead of setting NEED_INSTALL=true (managed by Xcode/CLT, not the package manager)
• Guard GITHUB_PATH update behind XMAKE_WAS_MISSING — previously the xmake PATH update ran whenever GITHUB_PATH was set, even if xmake was already present; now gated on a new XMAKE_WAS_MISSING flag set only when xmake is detected as missing at dependency-check time:

  check_dependency "xmake" "XMake" || { NEED_INSTALL=true; XMAKE_WAS_MISSING=true; }
  # ...
  if [ "$XMAKE_WAS_MISSING" = true ] && [ -n "$GITHUB_PATH" ]; then
