* fix(feedback): pre-include Orca version and OS in errors and feedback
Make terminal errors and Send Feedback carry easy-to-copy client
environment details so bug reports include build and platform context
without a follow-up ask.
* fix(feedback): satisfy exhaustive-deps in environment prefill hook
Destructure hook params so useEffect/useLayoutEffect dependency lists
are complete and the changed-code quality gate passes.
* fix(preload): stop importing node:os in sandboxed preload
Sandboxed Electron preloads cannot require node:os. That import crashed
the whole preload script, leaving window.api undefined and taking down
App chrome (dock badge, preflight). Keep platform.get on process APIs
only, and guard best-effort badge/preflight callers when api is missing.
* fix(feedback): count text typed below the env footer
Strip only the prefilled Orca/OS/Shell block for Send validation so
users who click past the footer and type can still submit.
