Remote file store gains create preconditions and cancellation

Under the hood
Useful2 Signal3
Remote File Store

Remote file creates can refuse to overwrite an existing file and both calls accept cancellation.

A not_exists precondition exists on remote create, with no caller in this build requesting it.

What

The remote file store's create call takes an options argument that can attach a not_exists precondition, so a create fails rather than overwriting, and both create and update now accept an abort signal. Nothing observed in this build requests the precondition, so whether any caller uses it is not settled here.

Evidence

"not_exists"

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