Two release-blocking bugs traced to the same root cause: the unanchored
`data/` rule in .gitignore matched server/src/ledgrab/data/, which is
where shipped package assets live (prebuilt sounds, game adapters).
The files were never `git add`-able without -f, so they never reached
the v0.4.2 tag and CI builds couldn't include them.
- .gitignore: anchor /data/ and /server/data/ so nested package data
dirs are not ignored.
- Track previously-excluded shipped assets:
- server/src/ledgrab/data/prebuilt_sounds/{alert,bell,chime,ping,pop}.wav
- server/src/ledgrab/data/game_adapters/{minecraft,rocket_league,valorant}.yaml
- Bump _FALLBACK_VERSION 0.3.0 -> 0.4.2 to match pyproject.toml.
The Windows installer strips ledgrab-*.dist-info, so
importlib.metadata falls back to this literal — which is why
v0.4.2 reports v0.3.0 in the WebUI.
- Patch _FALLBACK_VERSION at bundle time in build-common.sh and
build-dist.ps1 so future drift is auto-corrected by the build.
Declutters the repo root by consolidating build-common.sh,
build-dist.sh, build-dist-windows.sh, build-dist.ps1, and installer.nsi
into build/. Updates all path references in CI workflows, NSIS installer,
and documentation.
