## Summary
- Extends `androidRoots()` to fall back to OS-default Android SDK
install paths after `ANDROID_HOME` / `ANDROID_SDK_ROOT` come up empty
- Covers Android Studio defaults (`~/Library/Android/sdk` on macOS,
`~/Android/Sdk` on Linux) and common system-wide paths
(`/opt/android-sdk`, `/usr/lib/android-sdk`, etc.)
- Fixes the case where an MCP server spawned by a GUI process (Claude
Code desktop, VS Code) doesn't inherit the shell-exported
`ANDROID_HOME`, causing argent to silently fail to find `adb`/`emulator`
even on a correctly configured machine
## Stacking
Stacked on `feat/linux-host-support`. Base will be retargeted to `main`
after that PR merges.
## Test plan
- [ ] New tests in `android-binary.test.ts` cover the Studio-default
paths and the `ANDROID_HOME` priority invariant
- [ ] `npm run test -w packages/tool-server` passes
This PR adds tests for #148.
## Summary
Moves the Android emulator branch's test coverage out of #148 so that PR
can be reviewed without the test churn. This branch adds the test files
back on top of the (now test-stripped) base branch.
Tests inseparable from source changes (`describe-tool`,
`workspace-reader`, `workspace-reader-integration`) and the
`boot-simulator.test.ts` deletion stayed on #148 - base PR's CI passes
on its own.
## Test plan
- [x] `npx tsc --build` — clean
- [x] `npx prettier --check .` — clean
- [x] `npm test --workspaces --if-present` — 585/585 tool-server tests
pass; all other workspaces green
