chore(v1.1.9): clippy clean — workspace -D warnings

Surfaced + fixed during the F3 attestation:

- executor-core/sdk/queue.rs: drop redundant .map(|()| ()) call sites;
  enqueue_blocking discards QueueMessageId via .map(|_id| ()) (intentional)
- executor-core/sdk/retry.rs: hoist use std::collections::hash_map::DefaultHasher
  + use std::hash::Hasher to the top of the file (clippy::items_after_statements);
  replace `as i64` casts with i64::try_from + clear comment about jitter
  bound (clippy::cast_possible_wrap)
- executor-core/sdk/invoke.rs: move _LIMITS_IS_COPY const before #[cfg(test)]
  mod tests (clippy::items_after_test_module)
- manager-core/dispatcher.rs: dispatch_one_queue gains #[allow(too_many_lines)]
  (it's the queue tick's whole logic — split makes it less readable than
  the lint); .map(...).unwrap_or(default) → .map_or(default, ...)
- picloud/lib.rs: Limits { trigger_depth_max, ..Limits::default() } via
  struct-update instead of let-mut-assign (clippy::field_reassign_with_default)
- tests: r#"..."# → r"..." where there are no `"` inside (clippy::needless_raw_string_hashes);
  combine InvokeTarget::Name | InvokeTarget::Path arms with identical bodies
  in sdk_invoke.rs (clippy::match_same_arms)
