engineer 7e9b3981c3 fix(directory-picker): address review — modal layering, root nav, stale state
- HIGH: the "Browse Folders..." entry in the New Session RN <Modal> expanded
  a sibling BottomSheet, which a native Modal always covers (a
  BottomSheetModal through the root portal would be covered too), so the
  primary entry point was invisible/untouchable. The modal is now closed
  before the sheet expands and restored on cancel via a new onDismiss
  callback (restoreNewSessionOnDismiss ref); picking a folder proceeds to
  session creation without reopening the modal.

- MEDIUM: parentOf("/") returned "/" so Up at the POSIX root looped forever;
  it now returns null at "/", "\" and Windows drive roots alike, disabling
  the Up button there.

- LOW: opening the sheet with no known start directory (server home not
  loaded yet) showed the previous open's stale entries; it now clears state,
  invalidates in-flight loads, and shows an "Enter a path above to start
  browsing" empty state. Sheet init also no longer re-runs on snap-point
  drags (wasOpen guard).

- Extracted the pure path helpers (stripTrailingSlash/parentOf/nameOf) into
  src/lib/path-utils.ts (no RN imports) with node --test coverage for POSIX
  root, Windows drive roots, trailing slashes, and backslash paths.

typecheck clean; 97/97 tests pass (16 new).
