Fix ARG scoping in Dockerfile.distroless

ARG declarations before FROM are only available within the FROM
instruction and go out of scope afterward. Re-declare ARCH and OS
after FROM so they're available for the COPY instructions.
This fixes the build failure where ${OS}-${ARCH} resolved to empty
strings, causing "not found" errors for .build/-/prometheus.

* feat(notifier): independent alertmanager sendloops
Independent Alertmanager sendloops avoid issues with queue overflowing
when one or more Alertmanager instances are unavailable which could
result in lost alert notifications.
The sendloops are managed per AlertmanagerSet which are dynamically
added/removed with service discovery or configuration reload.
The following metrics now include an extra dimention for alertmanager label:
- prometheus_notifications_dropped_total
- prometheus_notifications_queue_capacity
- prometheus_notifications_queue_length
This change also includes the test from #14099

Fix multi-arch support for distroless Docker image
...
The distroless Dockerfile was using a hardcoded SHA256 digest that
referenced only the amd64 image, preventing builds for other
architectures. This caused the main-distroless tag to only publish
amd64 images while the regular main tag had all 5 architectures.
Changes:
- Use architecture-specific image tags (nonroot-${DISTROLESS_ARCH})
instead of SHA256 digest to enable multi-arch manifest resolution
- Add DISTROLESS_ARCH build arg to handle architecture name mapping
(armv7 -> arm) between Prometheus and distroless conventions
- Move ARG declarations before FROM to support variable substitution

tsdb: add auto-cleanup to newTestHead and remove redundant cleanup calls ( #17890 )
...
Add automatic cleanup to newTestHeadWithOptions so that heads created
with newTestHead are automatically closed when the test ends. This
simplifies test code by removing the need for manual cleanup in most
cases.
Changes:
- Add t.Cleanup in newTestHeadWithOptions immediately after creating
the head, using _ = h.Close() to handle double-close gracefully
- Remove redundant t.Cleanup, defer, and explicit Close calls from
tests that use newTestHead
- Add cleanup for heads created with NewHead directly in restart
patterns (e.g., restartHeadAndVerifySeriesCounts, startHead)

OTLP: label caching for OTLP-to-Prometheus conversion to reduce allocations and improve latency ( #17860 )
...
* otlptranslator: add label caching for OTLP-to-Prometheus conversion
Add per-request caching to reduce redundant computation and allocations
during OTLP metric conversion:
1. Per-request label sanitization cache: Cache sanitized label names
within a request to avoid repeated string allocations for commonly
repeated labels like __name__, job, instance.
2. Resource-level label caching: Precompute and cache job, instance,
promoted resource attributes, and external labels once per
ResourceMetrics boundary instead of for each datapoint.
3. Scope-level label caching: Precompute and cache scope metadata labels
(otel_scope_name, otel_scope_version, etc.) once per ScopeMetrics
boundary.
4. LabelNamer instance caching: Reuse the LabelNamer struct across
datapoints within the same resource context.
These optimizations significantly reduce allocations and improve latency
for OTLP ingestion workloads with many datapoints per resource/scope.

UI: Fix broken Y axis after graph page reload ( #17869 )
...
* UI: Fix broken Y axis after graph page reload
The new `y_axis_min` setting was always encoded into the URL, even if its value
was `null` (in which case it would be set to an empty string parameter). On the
decoding side, this wasn't taken into account correctly, and we tried to parse
the empty string as a float, causing completely broken graphs showing nothing
after reloading the graph page with such URL parameters.
I'm doing two things now:
* For the future, only encode the Y axis min into the URL if it's set at all,
similar as we do for the `end_input` and `moment_input` fields.
* On the decoding side, accommodate people (at least for now) who already saved
some links with the empty `y_axis_min` parameter by treating an empty string
as `null` instead of a number.

The benchmark was passing appendMetadata=false to NewCombinedAppender,
which caused UpdateMetadata to never be called on the underlying
noOpAppender. This resulted in app.metadata always being 0, failing
the assertion that metadata count should be positive.
Fix by enabling metadata appending in the benchmark.
