test: add golden-handles regression check to full-sync skill
- golden-handles.txt: 25 commonly-known mainnet handles (cardano, hosky,
minswap, bigpey, charles, ... incl. enterprise-address eth/satoshi/crypto),
all verified present on mainnet. Names only — handles are transferable NFTs,
so addresses are asserted by shape + round-trip, not pinned (drift-proof).
- run-golden-handles.sh: forward lookup (well-formed addr1.../stake1...) +
reverse-by-payment-address round-trip for each golden handle.
- run-rest-spotchecks.sh: fix stdin/heredoc collision (data now passed via
argv, not a pipe that the heredoc program shadowed) and switch the DB sampler
to JSON output so arbitrary UTF-8 handle names parse safely; skip empty names.
- SKILL.md: document the golden step and files.
Validated live against the in-progress mainnet sync: golden 25/25, sample 10/10.
