… router Adds the otter CLI subcommand which wires together: - local posix backend with Af2Desc metadata storer + Af2MPUHandler (write-at-offset) + same-dir-tmp atomic rename - Router distributing objects across N AF2 channels by stable key hash - one s3proxy forwarder per non-self slot (re-signed, UNSIGNED-PAYLOAD, plaintext intra-cluster for v1) Flags: --owner-map (shared JSON slot config), --self-idx (this node's slot), --forward-timeout (deadline for forwarded byte-writes). AF2-specific posix flags (--af2-desc, --same-dir-tmp, --disableotmp) also exposed. Jira: CDM-557247 Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

--owner-mapstatic file flag will be replaced with theOtterControlThrift server (port 9200, mTLS), CRDB client for grant read-back and startup warmup, in-memory grant cache, and 503/403 split in the S3 auth layer. Forward credentials will be moved to Vault rather than environment variables.Test Plan:

Revert this PR. Removes the
ottersubcommand from the binary; all other subcommands (posix,s3, etc.) are unaffected.
