joakimp 3d632ef02f Detect workspace UID and GID independently in entrypoint
The auto-detection block was gated on UID mismatch alone: if the host
user already had UID 1000 (the container's default) but a non-default
GID, the GID was never adopted. That left host-written files with a
numeric GID the container couldn't resolve to a name (e.g. '1001' on
Debian VMs where useradd assigns a dedicated group starting at 1001).

Split UID and GID detection into independent conditions. Each dimension
is adopted from /workspace if its env var is unset and the workspace
value differs from the container default, regardless of the other
dimension's state. Preserves existing USER_UID / USER_GID overrides.
