* fix: recognize boolean and varied integer formats for guest exec exited status
The guest-agent schema declares 'exited' as a boolean, but the PVE API
may return it in different formats: as a JSON boolean true, or as integers
1/0, or string '1'/'0'. The cmdlet was only checking for long 1L, causing
it to timeout on any PVE build that passed a boolean true unchanged.
Add ApiValueHelper.IsExited() to normalize these values and recognize
true, 1L, 1, and '1' as exited. Update the polling loop to use it.
* test: add integration tests for ApiValueHelper with real JSON payloads
Add tests that feed JSON data through the actual JsonHelper.ToNative
parsing pipeline to verify ApiValueHelper.IsExited correctly recognizes
boolean true and numeric 1 values as they arrive from the PVE API.
These tests pin the contract between the JSON parsing layer and the
value-recognition logic, ensuring the fix for issue #141 works end-to-end
with real API response shapes.
* fix: restore correct IsExited implementation with type checks
The helper must handle boolean true, long/int 1, and string "1" as the
issue specifies. This restores the correct multi-type check that was
inadvertently reverted.
* fix: correct boolean value handling in IsExited
