Replace llm_completion_user_turn_stop_strategies() with FilterIncompleteUserTurnStrategies

Browse Source 
Wrap the detector chain with `deferred(...)` and append the LLM
completion gate via a `UserTurnStrategies` specialization rather than
a free-standing helper, mirroring the existing
`ExternalUserTurnStrategies` pattern. The class lives next to other
strategy containers in `pipecat.turns.user_turn_strategies`, so users
discover it where they're already configuring `user_turn_strategies`.

The deprecated `filter_incomplete_user_turns` flag now rewires
through `FilterIncompleteUserTurnStrategies` under the hood, keeping
the migration path identical to before. `deferred(...)` stays public
as the explicit escape hatch for non-default compositions.

- Added `llm_completion_user_turn_stop_strategies()` in `pipecat.turns.user_turn_strategies` — a one-call helper that pairs default (or user-supplied) stop strategies, each wrapped with `deferred(...)`, with `LLMTurnCompletionUserTurnStopStrategy`. Common case: `stop=llm_completion_user_turn_stop_strategies()`.
- Added `FilterIncompleteUserTurnStrategies` in `pipecat.turns.user_turn_strategies` — a `UserTurnStrategies` specialization that wraps the detector chain with `deferred(...)` and appends `LLMTurnCompletionUserTurnStopStrategy` as the finalizer. Common case: `user_turn_strategies=FilterIncompleteUserTurnStrategies()`. Pass `config=UserTurnCompletionConfig(...)` to customize timeouts and prompts.

- Deprecated `LLMUserAggregatorParams.filter_incomplete_user_turns`. Add `LLMTurnCompletionUserTurnStopStrategy` to `user_turn_strategies.stop` instead (typically via `llm_completion_user_turn_stop_strategies()`). Setting the legacy flag still works for one release: the aggregator emits a `DeprecationWarning`, wraps existing stop strategies with `deferred(...)`, and appends the new finalizer strategy.
- Deprecated `LLMUserAggregatorParams.filter_incomplete_user_turns`. Use `user_turn_strategies=FilterIncompleteUserTurnStrategies()` (or add `LLMTurnCompletionUserTurnStopStrategy` to a custom `user_turn_strategies.stop`) instead. Setting the legacy flag still works for one release: the aggregator emits a `DeprecationWarning` and rewires the strategies as if you had passed `FilterIncompleteUserTurnStrategies` directly.
