Problem

The rendered PowerShell profile launches Git Bash, sources shell/common.sh, prints the full environment, and reparses it on every PowerShell startup. Local measurements show that bridge adds roughly one second at the median and occasionally several seconds.

Outcome

The Warp renderer emits the required Windows environment and PATH setup without launching Bash during PowerShell startup.
Shared values retain one canonical owner and do not drift between shell implementations.
Warp rendering tests cover the native PowerShell output.
ward exec warp-test and repository pre-commit validation pass.
