* docs: loud deprecation of badger v1 datastore
badger v1 (go-ds-badger) has not been maintained by its upstream
maintainers for years and has known bugs (startup timeouts, shutdown
hangs, fd exhaustion). make the deprecation loud and unavoidable:
- print ERROR log line and bordered stderr message on every daemon
start when a badger-based datastore is detected
- mark badgerds and badgerds-measure init profiles as DEPRECATED
- update docs/datastores.md and docs/config.md with migration guidance
- add changelog highlight for v0.40
badger v1 support will be removed later in 2026.

Pebble provides a high-performance alternative to leveldb as the datastore, and will serve as a replacement for badger1.
There are a number of tuning parameters available for tuning pebble's performance to your specific needs. Default values are used for any that are not configured or are set to the parameter's zero-value.
