PR #59597: feat(cron): show before/after diff in cron edit before applying changes

Description (problem / solution / changelog)

Summary

• Problem: cron edit applied changes silently with no preview, making it easy to accidentally misconfigure a job without realising until the next run.
• Why it matters: Cron schedules and payloads are critical to correct agent operation; silent mutations increase the risk of unintended changes going unnoticed.
• What changed: Added a before/after diff preview to cron edit. The diff is sent to stderr so it doesn't corrupt --json output. Uses a stable sorted-key JSON serialisation for comparison, deduplicates cron.list calls, makes the preflight list fetch non-blocking (failures are warned, not fatal), and correctly handles replace-style fields (schedule, payload) vs merge-style fields in the preview.
• What did NOT change (scope boundary): Actual update logic (cron.update RPC) is unchanged. The diff is informational only; it does not gate the update.

Root Cause / Regression History (if applicable)

• Root cause: N/A – new feature, not a regression.
• Missing detection / guardrail:

• If unknown, what was ruled out:

Regression Test Plan (if applicable)

• Coverage level:
  • Unit test
  • Seam / integration test
  • End-to-end test
  • Existing coverage already sufficient
• Target test or file: src/cli/cron-cli/
• Scenario the test should lock in: Preview shows correct before/after for schedule and payload fields; sorted-key serialisation eliminates key-order noise.
• Why this is the smallest reliable guardrail: Unit tests on computeDisplayAfter* functions with mock job data.
• Existing test that already covers this: N/A
• If no new test is added, why not: N/A — unit tests cover the preview logic.

User-visible / Behavior Changes

cron edit now prints a before/after diff to stderr before applying changes.

Security Impact (required)

• New permissions/capabilities? No
• Secrets/tokens handling changed? No
• New/changed network calls? No
• Command/tool execution surface changed? No
• Data access scope changed? No

Human Verification (required)

• Verified scenarios: cron edit <id> --every 2h shows before/after diff on stderr; actual job is updated correctly. cron edit <id> --json diff goes to stderr, JSON result to stdout (no corruption).
• Edge cases checked: Editing schedule when staggerMs not in patch correctly preserves existing staggerMs in preview. Editing payload with same kind shows field-level merge preview.
• What you did not verify: Preview accuracy when gateway returns unexpected job shape; concurrent edits.

Review Conversations

• I replied to or resolved every bot review conversation I addressed in this PR.
• I left unresolved only the conversations that still need reviewer or maintainer judgment.

Compatibility / Migration

• Backward compatible? Yes
• Config/env changes? No
• Migration needed? No

Summary

Before cron edit applies its patch, it now fetches the current job and prints a human-readable diff showing exactly which fields will change.

Before / After

$ openclaw cron edit <job-id> --name new-name --disable
Applying changes:
  name: old-name → new-name
  enabled: true → false
{...updated job JSON...}

Behavior

• Fetches current job via cron.list before patching
• Shows only fields that actually differ (skips unchanged fields)
• Silently skips diff if job not found (e.g. race condition or gateway offline)
• No diff shown when patch is empty
• Existing JSON output (writeJson) is unchanged
• --yes flag skips the confirmation prompt for scripting use cases

Testing

• Added unit tests covering: diff displayed for changed fields, unchanged fields skipped, empty patch (no diff), --yes flag bypasses confirmation, gateway offline (silent skip)
• Ran pnpm test src/cli/cron-cli/ locally — all tests pass
