Allocates sea-level for noaa/8655875 (Atlantic, NC), which enters the bundled tide catalogue with @neaps/tide-database 0.9.20260907, and tombstones long-key-lake for noaa/8723887, which leaves in the same revision.
The tombstone is a retirement, not a deletion: it stops a later station inheriting a URL that used to mean something else, and if Long Key Lake returns — it left through an upstream catalogue revision rather than a decision here — buildSlugTable hands its own slug back rather than minting a fresh one.
Unblocks openwatersio/slackwater-ios#315.
