* test: add Pezkuwi's own chains to the balance test fixture
Nova's upstream fixture only covers chains it knows about - Pezkuwi (relay),
Pezkuwi Asset Hub, and Pezkuwi People never had test coverage at all, since
they don't exist in Nova's world. This adds them as a pure addition on top
of the existing filter+override pipeline, so the published
chains_for_testBalance.json now covers exactly what our merged chains.json
actually contains: Nova-inherited chains + our own ecosystem.
Test account is the mainnet Founder key, verified live via @pezkuwi/api on
2026-07-09 against all three chains: substantial non-zero, non-frozen free
balance and a high nonce (actively used) on each - not a guessed or reaped
account. See pezkuwi-overlay/tests/pezkuwi_chains_for_testBalance.json for
the exact verified figures.
* chore: retrigger CI now that master triggers are fixed
