test(e2e): implement generator option scenarios

[LayZeeDK]

Parent: #319

Title: Implement generator option scenarios for move-file suite

Summary
Create scenario modules exercising all move-file generator option pathways: projectDirectory, deriveProjectDirectory, skipExport, skipFormat, allowUnicode, removeEmptyProject. Each scenario asserts critical invariants (file relocation, import/export rewrite behavior, project removal where applicable).

Objectives

• Ensure option flags produce expected side effects without regressions.
• Provide isolated, minimal fixtures per scenario (2 libs; optional app where needed).

Scope / Scenario Details

1. MOVE-PROJECT-DIR
   • Input: projectDirectory explicitly set.
   • Assert: Target project created at specified path; exports updated; no duplicate entries.
2. MOVE-DERIVE-DIR
   • Input: deriveProjectDirectory=true (mutually exclusive with projectDirectory).
   • Assert: Derived path matches derivation algorithm (based on original path segments); imports updated.
3. MOVE-SKIP-EXPORT
   • Input: skipExport=true for exported file.
   • Assert: Index file unchanged; no dangling exports.
4. MOVE-SKIP-FORMAT
   • Input: skipFormat=true.
   • Assert: Target file exists unformatted (detect via simple heuristic: presence of intentionally mis-spaced content) while move succeeds.
5. MOVE-UNICODE
   • Input: allowUnicode=true with source file containing Unicode characters in filename.
   • Assert: Move succeeds; path sanitized only per security rules; imports updated.
6. MOVE-REMOVE-EMPTY
   • Input: last remaining source files moved out.
   • Assert: Original project removed (project.json deletion) or marked empty per generator behavior.

Tasks

• Implement run() for each scenario with workspace scaffold via harness.
• Add focused assertions (avoid broad tree diffs).
• Reuse publish/install pre-check from orchestrator.
• Add minimal helper for import path validation.
• Add scenario registration in orchestrator catalogue.

Acceptance Criteria

• All six scenarios pass.
• Each scenario fails if its core invariant regresses (e.g., skipped export incorrectly updated).
• Unicode scenario validated on Windows & Linux locally (path length + characters) without errors.

Dependencies

• Harness utilities; orchestrator target.

Out of Scope

• Performance measurements; non-option scenarios.

Definition of Done
Scenario files merged; orchestrator executes them; docs list option coverage; linked in #319.
