* docs(integrations): fix unresolvable imports and stale API claims
* docs: apply style pass and drop out-of-scope import cleanup
* docs(integrations): address review feedback on gcs, cloud-trace, reflect-and-retry
Restore the gcs_ tool name prefixes in the GCS tool tables, since both
toolsets set tool_name_prefix="gcs" and the tables list names as the
model sees them. Use the current Agent Platform SDK name in cloud-trace
prose, make the reflect-and-retry failure description language-neutral
for Python and Go, and drop the redundant re-export clause.
* docs(gcs): note that tool_filter matches unprefixed tool names
Tool filtering runs inside get_tools() against the unprefixed name, and
get_tools_with_prefix() applies the gcs_ prefix afterwards, so the names
in the tables are not the names tool_filter expects.
* docs(computer-use): drop unused Gemini and override imports
