-- Per-project Neovim config for the Daybreak repo.
-- Auto-sourced when nvim is started inside the repo, provided the user has
-- `vim.o.exrc = true` in their config (or runs `:set exrc`). Neovim 0.9+
-- prompts to trust this file on first load.

-- Commands added:
--   :DaybreakStageX86 [Config]   build x86 components via wine and stage
--                                them into Daybreak.Linux/bin/<Config>/...
--                                /{Injector,Api}/ (default Config: Debug)
--   :DaybreakRunLinux            run Daybreak.Linux via `dotnet run` in a
--                                terminal split (honors launchSettings.json,
--                                which easy-dot-net's launcher does not)
--
-- Note: a Linux/wine attach-debugger workflow was attempted (winedbg --gdb
-- stub *and* native Linux gdb -p attach), but both freeze GW reliably because
-- of ptrace/wineserver interactions that wine doesn't tolerate. For now,
-- prefer logging-based debugging via the API's console + log file in the
-- game directory (Daybreak.API<YYYYMMDD>.log next to Gw.exe).
