SC-056: Migrate Legacy Skill with -cskill Suffix and marketplace.json

Covers: FR-007, FR-005, Section 2.2 — Secondary flow: Migrate legacy skill Type: Happy Path

Given

A legacy skill directory my-tool-cskill/ exists with:
- SKILL.md with name: my-tool-cskill
- .claude-plugin/marketplace.json with non-standard fields (version, author, tags)
- Scripts and references from v3.x

When

The user invokes: "Migrate this skill to the new standard"

Then

The directory is renamed from my-tool-cskill/ to my-tool/
The name field in SKILL.md is updated to my-tool
The .claude-plugin/marketplace.json is removed (simple skill) or stripped to official fields only
An install.sh is generated
A README.md with cross-platform instructions is generated
Validation passes on the migrated skill

Verification Method

Method: Manual test

Steps:

Create my-tool-cskill/ with legacy structure
Invoke: "Migrate this skill to the new standard"
Verify my-tool-cskill/ no longer exists
Verify my-tool/ exists with updated files
Verify name: my-tool in SKILL.md
Verify .claude-plugin/ is removed
Verify install.sh and README.md exist
Run validation on my-tool/

Expected evidence: Directory renamed. Frontmatter updated. marketplace.json removed. install.sh and README.md present. Validation passes.
