fix(process): stop failing captures on tokens macOS cannot expose (#1057)

* fix(process): stop failing captures on tokens macOS cannot expose

On a busy macOS 26 host the residual process sweep fails every capture:
KERN_PROCARGS2 omits the environment of Apple platform binaries for any
caller and fails with EINVAL for processes owned by another account, so an
unrelated process created after the capture baseline escalates to a hard
cleanup failure with cleanup_incomplete.

Report environment withholding distinctly from the Darwin token reader by
reading the platform-binary flag through csops, carry the effective uid in
the process table, and re-read unresolved tokens with a bounded retry plus a
final liveness confirmation so transient exec and exit states settle.
Candidates whose token the OS provably withholds, foreign-uid candidates,
and candidates that exited during validation are now recorded as unverified
processes instead of failing an otherwise clean capture or being signaled.
Related candidates and every other unreadable candidate stay fail-closed.

* test(process): align ownership lanes with the uid-aware process table

The Darwin sweep reads the effective uid through ps, so the offline
verification lanes' syscall allowlists must accept the new argv in
verify-binary-layout and verify-evm-interface. The foreign-uid ownership
test requires POSIX process uids; skip it where the platform has none
(the curated Windows lane).

* fix(verify): recognize UID-bearing ownership process tables
