fix: dual-pass ring assembly — greedy then backtracking retry for small relations

For relations with <= 200 sub-ways, if the greedy pass leaves unused sub-ways,
retry the entire relation with pure backtracking. The greedy pass may consume
sub-ways needed by other rings. Use whichever pass produces more rings.

Planet build with dual-pass stitcher is writing index files — almost done. 947,423 admin polygons (same as the hybrid build — the dual-pass didn't change anything for admin assembly, meaning the 10 missing boundaries have > 200 sub-ways and were skipped by the backtracking retry).

Let me wait for it to finish and run the comparison.

No WARNs — these 10 relations succeeded in ring assembly but produced different ring counts than osmium. They're not failing; they're producing a different number of rings from shared ways. This is the frequency/assignment issue (like Krefeld), not a stitching failure.

Let me verify with the dedup comparison:

Same 10 missing. These aren't ring stitching failures — they're ring-to-relation assignment differences (like the Krefeld case in Germany). The relation produces rings, but our stitcher assigns different rings to different relations than osmium does at shared boundary points.

These 10 areas (0.0016% of 642K) have their boundary ring assigned to an adjacent relation in our build. The actual boundary polygon exists — it's just tagged with a neighboring admin area's name. The reverse geocoding impact is negligible: a query at the boundary of these 10 areas might return an adjacent district's name instead.

This is the same class of issue as the Germany Krefeld/Neuhaus case — inherent to per-relation independent assembly vs osmium's global segment graph. **Not fixable without replicating osmium's full assembler.**


Done! Same admin count (947,423) — the dual-pass didn't help because the 10 missing relations have > 200 sub-ways. The comparison will show same results as before. Let me verify quickly and report.

Still 10 missing (same as hybrid build). These 10 relations have > 200 sub-ways, so the dual-pass backtracking is skipped. Let me increase the sub-way limit to cover them — I just need to check their actual sizes won't cause exponential blowup.

No WARN lines — these relations produced rings but they don't match the baseline's rings by name|level. The greedy stitcher DOES produce rings for these relations, but they get assigned to different names (like the Krefeld swap). These aren't missing from the stitcher — they're frequency/name mismatches.

Now I see it clearly. The parallel build has Tres Esquinas but is **missing** Alto Los Cardales, Pringles, COVIMER 2, FOPROVI, Antonio Palacios, ATE II, RT 002, Residencial Melville, and Tres Esquinas|9. These relations' rings simply aren't being formed by our stitcher.

These are legitimate failures where the greedy stitcher picks the wrong branch. The relations have all ways present but the ring can't close because a wrong sub-way was consumed.

The 200 sub-way limit for the backtracking retry is too low. These relations likely have 4-22 outer ways which become more sub-ways after splitting. Let me just remove the limit — the 100K call budget already prevents exponential blowup.


732:    if (sub_ways.size() <= 200) { // only for small relations (avoid exponential blowup)


Edit

if (sub_ways.size() <= 200) { // only for small relations (avoid exponential blowup)

{ // Second pass: backtracking retry (100K call budget prevents exponential blowup)
