Migrate Wright to the canonical workshop-rs Program API #311

Depends on: wrightkit/workshop-rs#179 and a consumable workshop-rs candidate release

Goal

Migrate Wright's raw Workshop and cross-language integration surfaces to the canonical workshop-rs Program API and verify that product tooling no longer relies on workshop-rs storage/compatibility representation details.

Context

Wright owns product/integration behavior such as diagnostics, lint/analyze/inspect, validated edits, CLI/LSP/agent surfaces, and orchestration. Raw Workshop semantics, WIR/canonical program semantics, settings, catalog facts, validation, and emission remain owned by workshop-rs.

Scope

• Update Wright integrations that consume raw Workshop programs, semantic inspection, validation, edits, analysis, or emission to use the candidate public Program contract.
• Remove dependencies on workshop-rs arena/storage/node-ID or compatibility-path APIs that are not part of the 1.0 boundary.
• Keep Wright-specific diagnostics/lint/analyze/inspect/edit orchestration in Wright.
• Verify raw Workshop product workflows against the candidate API and released owner contract.

Non-goals

• Reimplementing Workshop semantics in Wright.
• Moving OPY or DEL/OSTW lowering into Wright.
• Unrelated Wright architecture cleanup or CLI redesign.

Acceptance criteria

• Wright's raw Workshop tooling operates through the canonical workshop-rs Program API.
• Wright does not depend on private/compatibility storage representation for ordinary Workshop workflows.
• Existing representative check/analyze/inspect/edit workflows preserve their declared behavior against the candidate release.
• Any missing Workshop capability is fixed in workshop-rs rather than duplicated or worked around in Wright.
