v0.0.0

The first open-source release of k4a, under the Apache License 2.0.

Added

• k4a, a terminal UI for Kafka in the style of k9s: topics, consumer
  groups, brokers, ACLs and their configuration; a live message tail with a
  message detail view; producing; creating and deleting topics and ACLs;
  growing partitions and changing replication; resetting group offsets; a
  regex filter on every list and a : command mode. --readonly blocks the
  mutating actions.
• Headless subcommands for the same operations (produce, consume,
  create-topic, describe-topic, topic-size, alter-config,
  alter-replication, list-acls, create-acl, delete-topic, verify),
  and search over a whole topic with key, value and header scopes, time
  bounds and partition filters.
• Connections over plaintext, TLS, SASL/SCRAM-SHA-512, mTLS and MSK IAM.
  AWS profiles (SSO, credential_process) resolve in-process through the
  AWS SDK; broker lists can come from SSM parameters.
• Named contexts in ~/.k4a/config.yaml, kubeconfig-style, with contexts,
  use-context and config subcommands.
• An opt-in local index (index.enabled) that serves repeated searches
  without rescanning, and an on-disk cache of search results. A search the
  index cannot answer with full recall falls back to a scan.
• k4a-index, a shared index daemon that tails an allowlisted set of topics
  and answers searches over gRPC, reporting its coverage so a client scans
  whatever it does not hold; and k4a-mcp, a Model Context Protocol server
  in front of it. k4a mcp serves the same search tool over stdio.
• Helm charts for k4a-index and k4a-mcp, and signed multi-arch images
  ghcr.io/blairham/k4a-index and ghcr.io/blairham/k4a-mcp.
• k4a upgrade, which replaces the binary with the latest release after
  checking it against the release checksums.
