Feat: make reconcile timeout configurable via --reconcile-timeout flag

[qiaoxincheng880624-sudo]

Problem

WorkflowRun reconcile timeout is hardcoded to 3 minutes in
controllers/workflowrun_controller.go. There is no way to configure
this value at runtime, which causes failures for large workflowruns
(1000+ steps):

failed to patch workflowrun status: client rate limiter Wait returned
an error: context deadline exceeded

The reconcile context expires at exactly 3 minutes, and the final
patchStatus call fails because the context is already dead when the
rate limiter's Wait(ctx) checks it.

Solution

• Add ReconcileTimeout time.Duration to Args struct
• Expose --reconcile-timeout flag (default: 3m to preserve backward compatibility)
• Use r.Args.ReconcileTimeout in Reconcile function

Usage

--reconcile-timeout=30m

Backward Compatibility

Default value remains 3m. No breaking change.

## Summary by cubic
Make the reconcile timeout configurable via the `--reconcile-timeout` flag to avoid context deadline exceeded errors on large workflow runs. Default stays 3m; behavior is unchanged unless you set it.

- **New Features**
- Added `ReconcileTimeout` to `controllers.Args` and a `--reconcile-timeout` flag in `cmd/main.go` (default: `controllers.DefaultReconcileTimeout`, 3m).
- `WorkflowRunReconciler` and `BackupReconciler` now use the configured timeout, falling back to `controllers.DefaultReconcileTimeout` if unset or invalid.
- Example: `--reconcile-timeout=30m`.

<sup>Written for commit dacf53597d7091d8ef374d782499100aadb0333c. Summary will update on new commits.</sup>
