## Why
The helper's native bindings require shared libraries before entering `main`, including for lifecycle calls. Helper-only packages cannot satisfy that requirement.
## What changed
Make `--runtime` mandatory in `third_party/voice/assemble_package.py` and require the `runtime` argument in `assemble()`. Always validate and include the prepared runtime, and update the voice host documentation to describe the requirement.
## Testing
Update assembly tests to supply prepared runtimes and verify that package manifests include runtime library hashes and `runtime.json` alongside the helper.

## What changed
- Add an optional `--runtime` input to `assemble_package.py`.
- Validate the runtime receipt, target, source manifest, plugin inventory, paths,
and file hashes before copying only the declared runtime files.
- Preserve each platform's runtime layout and record the copied files and
`runtime.json` in the package manifest.
- Recheck hashes after copying and remove the new output if assembly fails.
## Testing
Add package assembly tests for Linux, macOS, and Windows layouts, invalid
receipts and paths, modified inputs, symlinked directories, and copy-time
changes.

## Why
The root Python formatting pass only covered `scripts/`, leaving Python utilities elsewhere in the repository outside `just fmt` and `just fmt-check`.
## What changed
- Run the scripts Ruff formatter from the repository root.
- Exclude `sdk/python`, which has its own formatter pass, and `codex-rs/vendor`.
- Apply Ruff formatting to the newly covered Python files and update the formatter coverage test.

## What changed
- Add `VoiceHost` to resolve the packaged voice helper, launch it with an
allowlisted environment, perform the protocol handshake, and enforce bounded
shutdown and process cleanup.
- Preserve native executable path encoding in the pipe process APIs.
- Add `third_party/voice/assemble_package.py` to create a fresh package copy
containing a target-compatible helper and a provenance manifest with file
hashes.
## Testing
- Cover installed helper lifecycle, build matching, missing and symlinked
helpers, non-UTF-8 package paths, environment filtering, package validation,
target pairing, and failure cleanup.
