qwen-code/packages/cua-driver/scripts/install-local.ps1

# cua-driver-rs local installer (Windows). Builds release-mode from the
# current source tree and drops the resulting cua-driver.exe into the same
# install layout that scripts/install.ps1 produces — so a local build and
# a release install can coexist + the `current` junction can flip between
# them.
#
# Params mirror scripts/install.ps1 so the developer loop matches what
# end users experience:
#   -AutoStart      register the cua-driver-serve Scheduled Task at logon
#                   (Windows-native equivalent of macOS LaunchAgent).
#                   Default off; the post-install message prints the
#                   registration recipe so you can opt in later.
#   -NoPathUpdate   skip the auto-append of the bin dir to the User PATH.
#                   Mirrors install.ps1's flag.
#
# Always builds in `release` configuration to match what install.ps1
# hands users (the prebuilt zip from GitHub Releases is `--release`).
# Use `cargo build -p cua-driver` directly + invoke target\debug\cua-driver.exe
# if you specifically want a faster-to-compile debug binary.
#
# Not for end-users — `irm https://.../install.ps1 | iex` fetches a
# signed/built release from GitHub. This script is for the developer
# loop (rapid edit/build/test on a Windows host).
#
# Layout produced (matches install.ps1 — see its header for details):
#
#   <visibleBinDir>            [junction → currentDir]
#   <currentDir>               [junction → release dir, retargeted here]
#   <release dir>              [real dir, this script's output]
#     0.0.0-local-release-<target>\cua-driver.exe
#
# The version-string carries `-local-release` so it never collides with
# a real release dir and is trivial to garbage-collect.
