beezm 09d23127e7 rivers/03c: routing polish — lake-termination as a preference, lake-enders come home 
Two surgical refinements of rivers/03b's fix 3. Everything else (confluence,
the rim cap, the faithful default) unchanged. Courses only: no height mutated,
no water filled or created — asserted per seed by a raw-bit digest.

- FIX A (ISLA_LAKE_PREFER_RATIO, default 0.4): a dry-basin router goes to the SEA
  unless cost_lake < ratio * cost_ocean, i.e. unless a lake is materially cheaper.
  rivers/03b used "nearest of {ocean, lake}", which is exactly ratio < 1.0 and
  captured 12 rivers, halving the sea mouths. Both leg costs are now recorded for
  every router so the knob is readable off the table without a re-run.
- FIX B (OwnBasinLakeEnder): a natural lake-ender terminates at the water inside
  its OWN terminal basin at any size. The 20,000 px significance threshold had
  exiled 999999937 #3 from its sub-threshold home lake, sending it ~5,800 px along
  the shoreline. The threshold still applies to routers choosing a distant lake.

As predicted, the rim cap re-arms: 31415926 #2 (66.7 m) now goes to the sea and
is refused, rather than being hidden in a lake.

Both fixes are off by default, so faithful mode still reproduces rivers/03 and
refined mode still reproduces rivers/03b.

Taste gate: nothing locked, nothing graduated.
