rootiest f9d400699f fix(agents-vault): keep the user's ssh command and drop the quadratic walk
The connect bound was delivered by injecting GIT_SSH_COMMAND, and an
environment variable outranks git's core.sshCommand -- so the guard,
which read only the environment, did not merely miss a configured ssh
command, it overruled one. A vault remote reachable only as
`ssh -i ~/.ssh/vault_key` failed to authenticate on every push, autopush
and --push alike, for the sake of a ten-second timeout. Both spellings
now count, and `set -qx` rather than `set -q` on the environment side so
an unexported fish variable -- which git never sees -- does not leave the
push with neither the user's ssh command nor a bound.

The agy knowledge walk appended each find with `set -a`, which rewrites
the whole variable every time; 500 files cost 21ms but 20,000 cost 58s,
on a path that runs in front of every agent launch. The walk now prints
NUL-separated and the list is built once, which is flat: the same 20,000
files take 707ms. NUL rather than newline because a filename may legally
contain one. What the walk collects, and its symlink and dot-led
semantics, are byte-for-byte unchanged.

Autopush is bounded by timeout(1) alone, so without it the launch path
was quietly back to an open-ended network call. It now says so and skips
the push instead; --push was never wrapped and is unaffected.
