perf(devframe): replace open with a native spawn helper

All three call sites (adapters/dev.ts, recipes/common-rpc-functions.ts,
plugins/assets's reveal-in-folder) pass a bare string target and never
use open()'s options - the npm open package is inlined via tsdown
onlyBundle with its full is-wsl/wsl-utils/run-applescript/
powershell-utils/default-browser* dependency tree, producing a ~19 KB
dist chunk for functionality a ~30-line spawn helper covers: darwin
'open', win32 'cmd /c start', linux 'xdg-open', with WSL detection
(/proc/version) preferring wslview and falling back to invoking
cmd.exe directly.

Drops the unused wait option along with the open dependency (and its
now-unreferenced transitive shims from tsdown's onlyBundle list) -
deliberate, narrow surface break; the utils/open subpath export is
unchanged. Verified the new implementation fails gracefully (ENOENT,
caught by the existing call-site try/catches) on a plain Linux
container with none of open, xdg-open, or wslview installed.
