Commit Message: fix(cli): implement plan diff --correction to show real correction attempt diff
Branch: fix/plan-diff-correction-stub

Background and Context

The specification (v3.2.0/v3.3.0) defines the agents plan diff command with a --correction flag:

agents plan diff (--correction <CORRECTION_ATTEMPT_ID>|<PLAN_ID>)

This command is supposed to show the diff for a specific correction attempt, allowing users to review what changes a correction would make before applying it.

Current Behavior:

The implementation in src/cleveragents/cli/commands/plan.py at the plan_diff function (around line 3296–3307) contains a stub:

if correction:
    # Show correction-specific diff (stub: shows info panel)
    console.print(
        Panel(
            f"[bold]Correction Attempt:[/bold] {correction}\n"
            f"[bold]Plan:[/bold] {plan_id}\n\n"
            "[dim]Correction diff will be available after M4.2.[/dim]",
            title="Correction Diff",
            expand=False,
        )
    )
    return

When a user runs agents plan diff --correction <CORRECTION_ATTEMPT_ID> <PLAN_ID>, they receive a placeholder panel saying "Correction diff will be available after M4.2." instead of an actual diff.

Expected Behavior

agents plan diff --correction <CORRECTION_ATTEMPT_ID> <PLAN_ID> should return a real diff showing the changes that the specified correction attempt would make (or has made) to the plan's decision tree and associated artifacts. The output should follow the same format as the regular plan diff command (supporting --format rich|plain|json|yaml).

Acceptance Criteria

agents plan diff --correction <CORRECTION_ATTEMPT_ID> <PLAN_ID> returns a real diff (not a stub/placeholder)
The diff shows which decisions were reverted or added by the correction
The diff supports all output formats (--format rich|plain|json|yaml)
The stub comment and placeholder text are removed

Subtasks

Implement CorrectionService.get_correction_diff() or equivalent method to retrieve diff data for a correction attempt
Wire the --correction flag in plan_diff CLI command to call the real diff implementation
Support all output formats (rich, plain, json, yaml) for correction diffs
Add BDD scenarios in features/plan_diff_artifacts.feature or a new feature file for the --correction path
Remove stub code and placeholder text
Run nox (all default sessions), fix any errors
Verify coverage >=97% via nox -s coverage_report

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly.
The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.

Supporting Information:

File: src/cleveragents/cli/commands/plan.py, function plan_diff (around line 3265–3318)
The stub comment explicitly says "Correction diff will be available after M4.2." indicating this was intentionally deferred
Related feature file: features/plan_diff_artifacts.feature (does not test the --correction flag path)
Spec reference: agents plan diff (--correction <CORRECTION_ATTEMPT_ID>|<PLAN_ID>) — Plan Corrections section

🔍 Triage Decision — [AUTO-OWNR-2]

Status: ✅ VERIFIED

MoSCoW: Must have
Priority: High
Milestone: v3.3.0

Reasoning: The agents plan diff --correction command returns placeholder text instead of a real correction diff, which is a stub implementation that directly violates the v3.3.0 spec. This must be fixed before the release.

Implementation Attempt — Tier 1: haiku — Success

Implemented the correction diff functionality:

Added correction_diff() method to PlanApplyService that retrieves correction attempt data from the database
Implemented helper functions for rendering correction diffs in multiple formats (rich, plain, json, yaml)
Updated the CLI command to call the new method instead of showing the stub placeholder
Removed the stub Panel display that showed "Correction diff will be available after M4.2"
