Three components:
1. WbMeshAdapter wraps the PrepareMeshDataAsync task with a continuation
that surfaces faulted-task exceptions + null-result cases for EnvCell
IDs only (gated by ProbeIndoorUploadEnabled). Two new log shapes:
[indoor-upload] FAILED cellId=0x... exception=<TypeName>: <Message>
stack=[<top 3 frames>]
[indoor-upload] NULL_RESULT cellId=0x...
2. Capture procedure: re-launch at Holtburg with the probe on, grep for
FAILED/NULL_RESULT lines, get definitive per-cell cause for the 26
missing-completion cells from Phase 1's capture.
3. Targeted fix: code change matching whichever exception type / null
pattern dominates. Fix shape is data-driven — see the contingency
table in the spec.
WB's catch at ObjectMeshManager.cs:589 already calls _logger.LogError,
but WbMeshAdapter constructs the manager with NullLogger.Instance, so
the log is dropped. Our continuation surfaces the same data scoped to
EnvCells only (avoids the thousands of GfxObj/Setup log lines a real
logger would emit during landblock streaming).
