Subject: [PATCH] fix(install): clear STUDIO_LOCAL_* env on POSIX normal
 install (#5146)

install.sh's normal-install branch passed the inherited parent-shell
environment to setup.sh without resetting STUDIO_LOCAL_INSTALL or
STUDIO_LOCAL_REPO. Consumers treat either as truthy:

  studio/setup.sh:491          checks STUDIO_LOCAL_INSTALL != "1"
  studio/install_python_stack.py:868  reads STUDIO_LOCAL_REPO, falsy
                                      if empty

Net effect: if a user or developer shell has stale STUDIO_LOCAL_*
exports from a previous --local run, a subsequent 'normal' install or
desktop-managed install silently takes the local-dev path: version
checks are skipped and an editable overlay points at the stale repo.

Fix mirrors install.ps1:1082-1087 on Windows: set STUDIO_LOCAL_INSTALL=0
and STUDIO_LOCAL_REPO= explicitly in the env prefix for the non-local
branch so setup.sh sees a clean state regardless of parent exports.
