feat(storage): harden internode data-path controls (#4224)

* fix(rio): propagate http writer shutdown errors

* fix(ecstore): unify remote lock rpc deadlines

* fix(storage): reject corrupt read multiple payloads

* feat(rio): add internode http tuning profiles

* feat(metrics): add internode baseline signals

* feat(ecstore): observe shard locality topology

* feat(ecstore): gate shard locality scheduling

* feat(ecstore): gate batch read version rpc

* feat(ecstore): observe batch processor adaptation

* feat(ecstore): gate batch processor observation

* docs: add get benchmark regression analysis

* docs: add issue 797 execution plan status

* fix(ecstore): require explicit batch rpc support

* fix(ecstore): honor documented batch read gate

* fix(ecstore): keep batch read gate stable per call

* chore: update workspace dependencies

* feat(ecstore): log batch read gate decisions

* feat(ecstore): count batch read gate decisions

* test(issue-797): add local internode A/B runner

* test(rio): fix tuning profile spelling fixture

* fix(protocols): adapt sftp channel open callbacks

* fix(metrics): wrap batch processor observation args

* chore(docs): keep issue notes local only

* fix(storage): address internode review feedback

* fix(storage): address internode data-path review findings

- Run the BatchReadVersion auto-mode unary fallback outside the batch
  RPC deadline so each read_version keeps its own per-op timeout and
  health accounting instead of racing the whole batch against one
  drive timeout.
- Cap adaptive batch-processor concurrency growth at a hard multiple
  of the configured baseline so sustained fast batches cannot ratchet
  past the configured limit.
- Parse RUSTFS_INTERNODE_HTTP_* tuning, RUSTFS_BATCH_PROCESSOR_ADAPTIVE,
  and RUSTFS_METADATA_BATCH_READ once per process instead of re-reading
  the environment on hot paths.
- Skip shard read-cost collection in observe mode when stage metrics
  are disabled, and cache the local endpoint host list instead of
  rebuilding it on every read.
- Allow --warp-extra-args values starting with -- and drop the unused
  warp_hosts_csv helper in the issue-797 A/B runner.
