docs: remove internal/flag-gated items from v0.23.0 changelog

The original v0.23.0 changelog (#120) included items that are either
behind production feature flags or relate to internal/poseidon
functionality not yet surfaced to users:

- /btw Side Questions (cli_enable_btw: staging-shard-0 only)
- auggie session stats (cli_enable_session_stats: STAGING only)
- Dev Deployment Warning (internal)
- VM Heartbeat (internal)
- Event Command changes (internal)
- Session Lock Handling (internal)
- Message Queue capacity bump (internal)
- Bug fixes related to cloud/poseidon mode (internal)

Git-Based Plugins is kept: its umbrella flag (enable_plugin_marketplace)
is fully enabled in production.
