This ensures that adding README.md files to subdirectories (as discussed
for new folders and integrations) won't result in them being included in
the published package.

When judge_model_config is None, LlmRequest raises a ValidationError
because it requires a config. We now construct a default GenerateContentConfig
if one isn't provided.

…actions

This change introduces logic to identify events containing requests for tool confirmation or auth credentials. The compaction process will now stop before any such "Human-in-the-Loop" (HITL) events, ensuring that the full context of the interaction is preserved and not summarized away. This applies to both sliding window and token threshold compaction strategies.

`part_to_message_block` iterated `content` char-by-char when a tool
returned it as a plain string (e.g. `LoadSkillResourceTool`'s
`{"content": <file text>}`), producing `"H\ne\nl\nl\no"` instead of
`"Hello"`. Guard the list branch with `isinstance(..., list)` and add
a sibling branch that passes a scalar string through directly, matching
Anthropic's `content: str | list[ContentBlockParam]` shape.

…ack as successful

Previously, an empty `candidates` list without `prompt_feedback` resulted in an `UNKNOWN_ERROR`. This change updates the logic to handle such cases as a successful completion with no generated content, which is valid for certain model interactions like tool-driven turns.

…ntTool

AgentTool.run_async only extracted text parts from the inner agent's
response, silently dropping code_execution_result.output and
executable_code.code. Outer agents using an inner agent with a code
executor saw nothing.

Adds @functools.lru_cache to find_context_parameter so the inspect.signature
+ typing.get_type_hints lookup runs once per function, not on every MCP
confirmation callback or declaration build. No public surface change.
