footprint_update_needed only ever came from comparing the installed marker
against a channel manifest, so it could not fire on a git or local install —
they have no channel to ask. Those are exactly the installs whose code tree is
synced by hand, i.e. the ones most able to drift, and the drift was silent: the
helpers in /usr/local/lib/libreportal could sit behind the code that calls them
with nothing reporting it. That is how this box ended up running a crowdsec
helper with no bouncer-traefik-rotate action while the tool that needs it
shipped.
init.sh is what bakes the marker, so the install tree's own init.sh is
authoritative for every mode. lpInstallTreeFootprintVersion reads it and
lpFootprintStale compares. Wired into both non-release branches of the WebUI
status generator, and into the local branch of the interactive update check,
which is where a local operator actually looks.
Fails safe: a tree older than the marker, or a missing init.sh, reports current
rather than warning — verified alongside the real stale case.
Also gives webuiSystemUpdateCheck the self-reload guard webuiGenerateAppsToolsConfig
already documents. The WebUI task service sources these once at startup, so
without it an edited generator keeps writing the old JSON from memory.
