Process markers gain a second, currently-unused start-time field

Process marker files can write an alternate start-time field, but that path is hard-coded off.

A second process start-time field exists in the writer, disabled by a constant predicate.

What

Process marker writing was routed through a helper that can emit an alternate start-time field, but the switch is off in this build.

Details
  • covers both the daemon/PID marker and the fleet gesture record
  • the helper emits either procStart or the new procStartFt, chosen by a predicate hard-coded to return false here
  • the on-disk shape is therefore unchanged; the reader already understands both fields
Evidence

procStartFt

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
