Replaces the fixed-retry commit loop with deadline-based exponential
backoff for long running CMS commit operations (cms_commit_timeout=1h, 5s-60s jitter)
to allow heavily contended CMS nodes time to commit transforms.

- Introduced LocalCommand marker interface to identify commands that execute purely locally without a JMX connection.
- Updated History command to implement LocalCommand.
- Updated CassandraCliHelpLayout to check for LocalCommand instead of calling execution-flow methods, safely suppressing JMX options for offline commands.

* Insert the actual PreInitialize entry in the distribute metadata log
table using a callback after the log is bootstrapped.
* Remove the implicit insert on subsequent commit, i.e. of the Initialize entry
* Enables the full specifics of PreInit to be encoded in the serialized form,
removing the special casing for the first CMS member and other nodes
* Correctly invalidate cached KeyspaceMetadata when in a pre-initialized state
* Update Host ids in the system.peers_v2 table directly following CMS initialization
* Initialise gossip/local host id after CMS initialization completes
* Clean up CMS initialization errors which occur after the PreInitialize stage

Adds an opt-in O_DIRECT write path for background SSTable producers,
bypassing the OS page cache for data that is unlikely to be re-read
soon after being written. Memtable flushes remain buffered.
Enabled via two new YAML knobs:
- background_write_disk_access_mode: standard (default) | direct
- direct_write_buffer_size: 1MiB (default; aligned up to FS block
size, auto-grown to fit a worst-case compressed chunk)
The path is gated by config, table compression being enabled, and an
OperationType allowlist in DataComponent. The allowlist is exhaustive
over OperationType: any new value left unclassified fails static
initialization.
Operations on the DIO path: COMPACTION, MAJOR_COMPACTION,
TOMBSTONE_COMPACTION, ANTICOMPACTION, GARBAGE_COLLECT, CLEANUP,
UPGRADE_SSTABLES, WRITE, STREAM (chunked receiver only), RELOCATE,
UNKNOWN (offline sstablesplit).
Operations off the DIO path:
- FLUSH (policy: just-flushed data is hot, keep in page cache)
- SCRUB (correctness: tryAppend needs mark/resetAndTruncate)
- Zero-Copy Streaming (bypasses DataComponent.buildWriter)
- Uncompressed writers (only CompressedSequentialWriter has a DIO
subclass in this change)
StartupChecks fails fast if 'direct' is requested on a platform/FS
that does not support O_DIRECT.

Adds missing @Test annotations to testPasswordUpdateRateLimiting and testPasswordUpdateRateLimitingDisabled.
Also fixes minor typos in comments and assertion strings.
Fix flaky CassandraRoleManagerTest by grouping per-role rate limit checks consecutively.

The implementation of this CEP adds the ability to plug-in custom compressors providers
which might delegate the de/compression to a specialized hardware. An operator does not
need to change any schema definition, the mere implementation of a compressor provider
put on a class path and its related configuration in cassandra.yaml will transparently
start to use appropriate compressor, e.g. backed by a specialized hardware.
