Address review F7/F8 on #1625:
F7 (verification): the onchain.ts `connected === false` branch reads /v1/listfunds
(CLN's own connected field) and only buckets balance as inactive — it is not the
listPeerChannels mirror and does no close logic, so the coercion activates nothing
there. Reword the mirror comment, which inaccurately implied onchain.ts consumes it;
the mirror simply keeps the documented backward-compat `connected` field defined.
F8: hardcode the rune path in create-rune.sh to /root/.lightning/rtl.rune so it
matches the volume mount, healthcheck and RTL runePath instead of deriving it from
${LIGHTNINGD_DATA}, removing the silent-divergence risk.

Address review F5 on #1625: create-rune.sh was a one-shot poststart script — if
the RPC wasn't ready within its poll or createrune failed, it exited without ever
writing rtl.rune, and since the cln healthcheck gates on that file and rtl waits
on service_healthy, a failed pass deadlocked the whole stack until 'down -v'.
Drive rune creation from the healthcheck instead: the script is now a quick,
idempotent single attempt, and the healthcheck runs it on every interval, so a
transient RPC-startup race just retries and self-heals. Moved the script out of
lightning-poststart.d to /opt and updated the healthcheck, compose comment and
README accordingly.
