exporterhelper: Update to v0.148.0 and preserve queue features

Rebase the Sawmills collector exporterhelper stack onto upstream v0.148.0 and keep the queue payload codec / in-memory encoding behavior intact.

Description

• Port the queue payload codec hook and make it order-independent.
• Add in-memory queue encoding with async decode-drop logging.
• Restore the exporterhelper module-tag workflow and changelog entries.

Summary by cubic

Sync main into the exporterhelper branch at Collector v1.54.0 (core v0.148.0). Preserves our queue payload codec/in‑memory encoding, adopts upstream exporter renames, and refreshes builder/mdatagen/telemetry/CI with profiles metrics, Unix socket HTTP binding, deprecated‑type aliases, service auto‑generated feature gates, and a /rerun CI command.

• New Features

  • pkg/exporterhelper: keep WithQueueBatchPayloadCodec and WithQueueBatchInMemoryEncoding; add profiles obs metrics.
  • Exporter renames: exporter/otlp → exporter/otlp_grpc, exporter/otlphttp → exporter/otlp_http (deprecated aliases kept; no config changes).
  • Builder (ocb): new init command; support a telemetry module; OS‑specific binary naming; expand deprecated aliases (including extensions) in generated factories; ignore aliases in component listing; default to Go 1.25.
  • cmd/mdatagen: add config schema generator; auto‑generate feature‑gate docs and code; support display_name; enable per‑metric configurable attributes with runtime reaggregation (aggregation_strategy) behind a feature gate; improved validation and tests.
  • Profiles: re‑enable batching; add receiver sample metrics; receiver/nop supports profiles; introduce scraper/xscraperhelper and AddProfilesScraper; deprecate AddScraper in favor of AddMetricsScraper; scraper error logs now include the scraper ID.
  • exporter/debug: support output_paths.
  • confighttp: bind Unix domain sockets; bound span name cardinality for unknown/invalid HTTP methods.
  • Service telemetry: detailed otelcol_exporter_send_failed_* metrics now include error.type and error.permanent; service feature gates are now auto‑generated.
  • pkg/confmap/xconfmap: add experimental raw string‑map API to avoid flattening internal types.
  • CI/Repo: add /rerun to retrigger failed workflows; refresh actions; add markdownlint; add AGENTS.md.

• Bug Fixes

  • pkg/exporterhelper/internal/queuebatch: fix ref‑count off‑by‑one in partition batcher to prevent premature completion and dropped errors.
  • cmd/mdatagen: avoid panic when run without args; fix reaggregation test generation when required attributes are present; correct handling of deprecated metric fields.
  • confmap: fix ExpandedValue sanitization for struct collections; include parent package in e2e coverage; add raw map support to keep internal types intact.
  • configoptional/confmap: ensure inner Unmarshal methods are invoked when wrapped in configoptional.Optional.
  • configgrpc: set client info before auth so authenticators see client details.
  • Builder: avoid duplicate CLI error logging on invalid commands.
  • pdata/pprofile: fix off‑by‑one dictionary lookup; mark removed aggregation elements as deprecated.
  • Service: don’t fail startup if process metrics registration isn’t supported on the OS.
  • CLI: ensure stable, sorted output for providers and converters in otel components.

[sawmills-architect-review]

[ARCH-REVIEW] COMMENT — No blockers or concerns. One nit; address before merge.

Large upstream rebase to OTel Collector v0.148.0 (core v1.54.0). Sawmills-specific additions — WithQueueBatchPayloadCodec, WithQueueBatchInMemoryEncoding, and the memory_queue.go in-memory encoding path — were all introduced in prior commits on this branch and are preserved cleanly here. The upstream queueCfg migration from queuebatch.Config → configoptional.Optional[queuebatch.Config] is correct; nil-safety guards updated throughout. Upstream off-by-one fix in partition_batcher.go ref-count path is included. No architecture concerns.
