Scope the stub publisher failure to node 00's output; when every stage-0
publish failed, the first failing sibling cancelled node 00 and its
recorded error was "context canceled" instead of the publish error.

F2: Execute had no status guard, so a redelivered or stale message reran a
finished run. Runs that are neither queued nor running are logged and acked
without work; "running" still executes so a worker that crashed mid-run
recovers.
F4: failRun, finishNodeFailed and MarkRunFailed wrote the terminal status on
the caller's context, which is exactly the context that is already cancelled
when the run failed because of a shutdown or a sibling node — the write was
refused and the run stayed stuck in "running". They now write on a
context.WithoutCancel copy with a 10s timeout; the consumer's best-effort
MarkRunFailed does the same.
F5: peak memory scaled with the host's core count. LP_MAX_WORKERS (default 8)
is now the total window-worker budget of a run and LP_MAX_NODES (default 2) the
node fan-out; each node gets max(1, workers/nodes) through the new
landscape.ComputeWithWorkers. Compute and service.ComputeFunc keep their
signatures: Compute delegates with MaxWorkersPerNode, and a legacy ComputeFunc
handed to NewLandscapeService is wrapped.
F6: the stage loop used a plain errgroup, so a failing node let its siblings
run to completion. It now uses errgroup.WithContext and passes the group
context into runNode, cancelling siblings mid-compute.
F7: wrap every float32 product in an explicit conversion so the compiler
cannot fuse it into an FMA, keeping the kernels bit-identical to numpy's
per-op rounding.
F8: README's builder package list now matches the Dockerfile (adds g++), and
the Landscape section documents the memory model and the two new knobs.

F1: ValidateFileContent rejected the pipeline's own output. GDAL writes a
BigTIFF header ("II+\0" / "MM\0+") whenever BIGTIFF=IF_SAFER kicks in for a
large raster, so accept both alongside the classic TIFF magic and reword the
error to "file is not a valid TIFF/BigTIFF GeoTIFF". GodalIO.Create now
delegates to an unexported createGTiff so a test can force BIGTIFF=YES and
assert the produced header passes the check.
F3: a user-supplied filename went straight into the S3 object key for dataset
uploads and for both dataset and dataset-group SLD uploads, so "../../x.sld"
escaped the dataset's own prefix. Reduce every such name to its base with a
shared safeObjectName helper, rejecting names with no usable base.
F9: rename the shadowing inner "raw" in the PATCH dg_id case to "s".
