Add a C2-guarded PWD handler that background fast-forwards the fish-config repo (baseline) plus any repos in a machine-local registry. Safety is guaranteed by _auto_pull_sync: clean tree + has-upstream + --ff-only, else no-op. Never rebases, merges, or overwrites work. - conf.d/auto-pull.fish: --on-variable PWD handler, throttled to fire once per repo entry; spawns a --no-config child to run the worker - functions/_auto_pull_sync.fish: the ff-only worker (safe on any branch) - functions/auto-pull.fish: add/remove/list/status registry management, usable even when C2 is disabled - completions/auto-pull.fish: subcommand + registered-repo completions Registry lives at ~/.config/.user-dots/fish/auto-pull.list (machine-local, never committed).

# SYNOPSIS
|
|
# __auto_pull_on_pwd (event handler, --on-variable PWD)
|
|
#
|
|
# DESCRIPTION
|
|
# On every directory change, checks whether the new $PWD is inside a
|
|
# registered repository (or the fish-config baseline) and, if so, kicks a
|
|
# background fast-forward. A throttle global ensures it fires once per
|
|
# repository entry rather than on every sub-directory change.
