* fix(shell): correct volume.list -writable filter unit and comparison
* fix(shell): correct volume.list -writable filter unit and comparison
* chore(shell): fix typo in EC shard helper param names
* fix(shell): use exact match for volume.balance -racks/-nodes filter
The old strings.Contains-based filter quietly included any id that was a
substring of the user-supplied flag value (e.g. -racks=rack10 also matched
rack1). Replace it with an exact-match set parsed from the comma-separated
flag value, and add regression tests for both -racks and -nodes paths.
Also fix a small typo in the "remote storage" error returned by
maybeMoveOneVolume.

* refactor(shell): drop nil sentinel in splitCSVSet, use len() in callers
* feat(shell): support batched EC encode and multi-volume selection
Add -volumeIds (comma-separated) and -batchSize flags to ec.encode.
When -batchSize > 0, volumes are processed in independent batches, each
committed separately: encode -> rebalance -> verify -> delete originals.
This bounds the working set and lets source volumes be reclaimed without
waiting for the entire set to finish, at the cost of per-batch rebalancing.
Because each batch deletes its originals, a failure in a later batch is
unrecoverable for already-completed batches.
To let the single-volume, multi-volume, and collection paths share one
per-batch routine, the re-balance scope is now always derived from the
volumes actually selected for encoding (collectCollectionsForVolumeIds),
rather than every collection matching the -collection regex. Practical
effect: with -collection, a collection that matches the pattern but
contributes no encodable volumes is no longer re-balanced as a side effect.
The -volumeId path is unchanged; -batchSize=0 (default) preserves the
original single-pass flow.
The per-batch routine reuses the existing assertEncodableRegularVolumes
guard, doEcEncode skipped-node handling, and verifyEcShardsBeforeDelete
retry loop. The capacity pre-flight check takes the already-fetched
topology instead of issuing another VolumeList to the master per batch.
Also clarify the -collection flag description to note it accepts a regex
pattern, matching the existing command help.
-volumeId and -volumeIds are mutually exclusive; ids in -volumeIds are
validated and de-duplicated.
* Rename `command_ec_encode_test.go` to `command_ec_common_test.go`.
All tests defined in this file are now for `command_ec_common.go`.
* Minor code cleanups.
- Fix broken `ec.balance` test.
- Rework integer ceiling division to not use floats, which can introduce precision errors.
* Introduce logic to resolve volume replica placement within EC rebalancing.
This will be used to make rebalancing logic topology-aware.
* Give shell.EcNode.dc a dedicated DataCenterId type.
