install.ps1

# install.ps1 — one-shot installer for the Claude Usage Dashboard tray app.
#
# Run from an interactive PowerShell session (no admin required for
# per-user Task Scheduler entries):
#
#     powershell -ExecutionPolicy Bypass -File .\install.ps1
#
# The script:
#   1. Locates trayapp.exe (next to the script unless -ExePath overrides).
#   2. Registers a per-user Task Scheduler "at logon" task so the tray
#      starts automatically (preferred over shell:startup; survives RDP).
#
# The price table no longer needs bootstrapping: the canonical prices.yaml
# is embedded in the binary (see prices_embed.go), so cost computation works
# with zero configuration. To override rates without a rebuild, drop a
# prices.yaml next to trayapp.exe or in %APPDATA%\usage_dashboard\ — see
# docs/configuration.md "Price table resolution".
#
# Re-running is safe: the scheduled task is replaced in-place.
#
# This script is documented in docs/tray-app.md ("Autostart") but not
# executed in CI — it's a Windows-only post-build step.
