build: strip the UTF-8 BOM that stopped both halves of the app starting

0.1.0-alpha.2 bumped three version strings with a tool that writes UTF-8
WITH a BOM, and committed it. Neither build survives that:

  package.json      vitefu JSON.parses the raw string, so `npm run dev`
                    exited instantly — "Unable to read package.json"
  tauri.conf.json   the Tauri build script failed with "expected value at
                    line 1 column 1"; cargo exit 101
  Cargo.toml        tolerated, but wrong

`require()` hides this. Node strips a BOM on require and JSON.parse does
not, so reading package.json from a REPL reports a perfectly good file
while both builds refuse it. Only the raw bytes show it: EF BB BF.

All 191 tracked files scanned. These three were the only ones affected,
and they are exactly the three 5682dfc touched. Stripped with Node rather
than PowerShell, whose default Out-File/Set-Content encoding is what wrote
them in the first place — the files are byte-identical but for the three
leading bytes.

Cargo.lock carries the 0.1.0-alpha.1 -> alpha.2 propagation the release
commit left behind in the working tree.
