* fix(setup): correct Windows sequencing wrapper quoting
* test(setup): preserve spaced Windows batch paths
* refactor(setup): dedupe PowerShell encoder, clarify wrapCmd comment
Route the Windows setup-sequencing and Hermes startup planners through the
shared renderer-safe encodePowerShellCommand instead of two verbatim btoa
copies, and make that shared encoder renderer-safe (Buffer is unavailable in
the sandboxed renderer where both planners also run). Reword the wrapCmd
comment so it describes the current single-outer-quote behavior instead of the
old quote-doubling bug.
* test(setup): cover Windows metacharacter paths
* fix(setup): keep Windows runner paths out of cmd source
* test(setup): preserve Windows setup failures
* docs(setup): explain safe cmd path handoff
