fix: switch skill removal to POST with JSON body instead of DELETE with query params

File paths as query parameters can fail due to URL encoding issues.
Switch to POST /kilocode/skill/remove with the location in the JSON
request body, which avoids encoding problems entirely.

Also log the SDK error response to aid debugging.
