* Fix balance hidden off-screen: put on own line below address bar

* Windows: inline mkdir in every rule, remove dir target that confused make

* Windows: move all target to top so it's the default rule

* Fix pool server not starting: always start when operator selected, re-sync dialog state on open

* Write debug.log to data directory (AppData/Roaming/Bitflash on Windows)

* Participant miner: use wallet address as username so payouts go to wallet

* Add .gitattributes to lock LF line endings, prevent CRLF drift

* Refactor pool mining to btf-only transport

* Persist pool settings and startup wiring

* Prune stale peers and expose pool queries

* Fix build regressions and add CLI mode/arg parity
