Closes #195

In dev mode the sidecar and ripgrep were staged as desktop/binaries/dreamcoder-sidecar-<triple> and desktop/binaries/rg-<triple>, while the CLI looks for a file named rg next to its own executable (src/utils/ripgrep.ts / ripgrepConfig.ts). So Glob and Grep only worked in bun run electron:dev when a system rg happened to be on PATH.

This follows the proposal in #195: the dev layout now matches the packaged one, with the triple as a directory instead of a file-name suffix.

• prepare-ripgrep.ts copies ripgrep to desktop/binaries/<triple>/rg[.exe] (new devBinariesDir helper).
• build-sidecars.ts writes the sidecar to desktop/binaries/<triple>/dreamcoder-sidecar.
• electron/main.ts starts the dev sidecar from binaries/<hostTriple>/ through a new devSidecarPaths helper in sidecar.ts, and uses that directory as appRoot, so rg sits next to the executable.
• electron-builder.json copies binaries/<triple> to bin for macOS and Windows instead of renaming the two files one by one.
• CONTRIBUTING_en.md and CONTRIBUTING_zh.md show the new path; CHANGELOG.md has an entry (existing checkouts need one more bun run build:sidecars).

ripgrepConfig.ts is unchanged, and DREAMCODER_TARGET_TRIPLE cross builds still do not overwrite the host build.

Tests: scripts/prepare-ripgrep.test.ts covers the staging directory, and the new desktop/electron/devSidecarPaths.test.ts covers the dev sidecar and ripgrep paths (with and without .exe) and checks that electron-builder.json copies each target directory to bin. The new tests fail on main; bun test scripts/prepare-ripgrep.test.ts, the vitest files above and tsc -p electron/tsconfig.json --noEmit pass. Not run here: bun run build:sidecars, bun run electron:dev without a system rg, and electron:pack on macOS and Windows, so the packaging change still needs that check.

This change was prepared with Claude Code (AI-assisted).

Thanks @pcbeingused333, this is the fix proposed in #195, and it is clean: the dev layout now matches the packaged one, electron-builder.json copies the whole target directory instead of renaming files one by one, and the old names are gone from the code and docs.

We ran it in the dev app on macOS (with no rg on PATH): the sidecar starts from binaries/aarch64-apple-darwin/, the file search finds files outside a git repo, and Glob and Grep work in a chat. The macOS and Windows packaging jobs pass too.

We pushed a merge of main on top to resolve the CHANGELOG conflict. Approving and merging. Thanks again!
