## Summary
- stop the macOS helper from unlinking caller-supplied socket and token paths
- keep parent-owned token cleanup tied to the helper startup that created it
- fail closed for non-socket socket-path collisions and cover helper cleanup races with regression tests
## Verification
- swift test --package-path native/computer-use-macos
- pnpm exec vitest run --config config/vitest.config.ts src/main/computer/macos-native-provider-client.test.ts
- pnpm run typecheck:node
- pnpm lint
- pnpm run build:computer-macos
- Electron/helper startup smoke validation
* fix(computer-use): stop malformed numeric args from crashing the agent
requiredNumber only checked isFinite, and several request handlers cast the
resulting Double straight to Int/UInt32 (elementIndex, clickCount, pages,
from/toElementIndex, windowId, windowIndex). Int(Double) traps when the value
is outside the integer's representable range, so a single malformed request
such as `{"elementIndex": 1e300}` crashed the entire agent process, killing
all in-flight automation.
Add a bounded conversion helper in the Core library and route every untrusted
Double->integer cast through it. boundedInteger truncates toward zero like
Int(Double) but returns nil (via init(exactly:)) instead of trapping when the
value is non-finite or out of range; the request handlers then surface a clean
invalid_argument error (or resolve to nil for the optional window lookups).
The helper lives in the Core library because the test target cannot import the
executable target where the handlers live. A negative-control run confirms the
out-of-range test traps with the previous Int(Double) cast and passes with the
fix.
* review: close remaining numeric crash paths
- parse stale-element validation indexes through bounded conversion
- reject malformed window selectors instead of dropping the target window
- bound synthetic scroll wheel deltas and cover Int32 conversion
