The client has had lint:size since #2612, the server had nothing, and
the server is where the biggest files live: maps.service.ts holds 3231
lines and grew by 200 in a month, and nine more services are past 1100.
scripts/size-lint.mjs carries the client's semantics over to src/ and
scripts/: a file may hold 1000 lines, the 23 that already hold more are
pinned at today's length in scripts/size-baseline.json, and --update
only ever lowers an entry.
A line past prettier's 120 columns counts once per 120 columns it spans,
so joining lines does not make room under the limit. The check fails
closed: a missing or malformed baseline or a missing src/ stops it
instead of passing with nothing checked.
