Previously the runner only stored a Result for successfully completed
tasks. Skipped and failed tasks had no entry in the results map, which
prevented guards from inspecting their status. Now every code path
(dep-failed skip, OnlyIfChanged skip, guard-false skip, failure, and
success) stores a Result with the appropriate Status field set.

Add HostResult struct for per-host responses in broadcast operations
and a HostResults slice field to Result. This enables downstream
tasks and guards to inspect individual host outcomes.

Add IsBroadcastTarget helper to detect broadcast/label targets,
extractHostResults to parse per-agent results from collection
responses, and isCommandOp to identify command operations. Update
executeOp to populate HostResults for broadcast targets and fail
on non-zero exit codes for command operations.

Add inter-task data access mechanism: TaskFnWithResults lets a task
closure receive the results map from prior tasks, enabling data flow
between dependent tasks. Add Data field to TaskResult so post-execution
result inspection can access task output data.

- Add TaskFnWithResults type and fnr field on Task
- Add NewTaskFuncWithResults constructor
- Update IsFunc() to account for fnr
- Add Data map[string]any field to TaskResult
- Update runner to handle fnr execution with lock-protected results
- Populate Data on TaskResult in success path
- Add TaskFuncWithResults method on Plan
- Fix Explain() to use IsFunc() for fnr task detection

Add TaskFuncWithResults, Result types (Status, HostResult, Data on
TaskResult), and broadcast results to docs. Update example to use
TaskFuncWithResults with Results access and show Data on TaskResult.

Rewrite examples/all to showcase low-level SDK patterns:
TaskFuncWithResults reading data from prior tasks, Status
inspection in When guards, alert-on-failure triggered by
StatusFailed, and Data extraction in post-run reporting.

Tasks with a When guard were being auto-skipped when a dependency
failed, preventing failure-triggered patterns like alert-on-failure.
Now tasks with guards bypass the dependency-failed skip and let the
guard decide whether to run. Also print all Data keys in the example
instead of only stdout/hostname.

The runner extracted the changed boolean from the API response data
but left it in the Data map, causing it to appear alongside real
fields in result output. Also switch example detailed results to
JSON formatting for readability.

Propagate HostResults from Result to TaskResult so AfterTask hooks
can display per-host data for broadcast operations. Add SetName
method to Task for renaming after creation.

Add WhenWithReason method to Task that allows setting a custom reason
string shown when a guard returns false, improving skip hook output.

Cover SetName and WhenWithReason with table-driven unit tests and
an integration test verifying custom skip reasons flow through OnSkip.
