Subject: [PATCH 1/2] Add sh-compatible path_prefix and path_postfix helpers
 for dynamic PATH

Introduce path_prefix and path_postfix in .profile to prepend and append
PATH entries while skipping duplicates. Refactor static PATH assignments to
use these helpers, source .profile from .bash_profile for login shells,
and replace the hardcoded opencode PATH in .bashrc with path_prefix.

Subject: [PATCH 2/2] Skip PATH entries when install directory is missing

path_prefix and path_postfix now require each directory to exist before
adding it to PATH. The opencode fallback in .bashrc uses the same check.
