[v0.2] Establish the language-provider boundary and canonical Workshop core

[Teakowa]

Roadmap: #134

Goal

Deliver Wright v0.2 as the first real multi-repository architecture release: neutral provider protocol, independent canonical Workshop core, and Wright-side integration without prematurely cutting over OPY/DEL production providers.

Release work

• [v0.2] Rebaseline language ownership and licensing boundaries #136 — accepted ownership/licensing architecture in Wright docs/ADR.
• language-provider-protocol#1 — LPP v1 and conformance.
• workshop-rs#1 — Workshop catalog/locale/provenance/version boundaries.
• workshop-rs#2 — canonical multi-locale Workshop core.
• [v0.2] Add LPP client, provider discovery, and process lifecycle #142 — Wright LPP client/provider discovery/process lifecycle.
• [v0.2] Cut Wright over to workshop-rs #143 — Wright cutover to workshop-rs and removal of duplicate canonical Workshop ownership.
• [v0.2] Route source mutation semantics through providers #139 — validated mutation/refactoring through the provider boundary.
• [v0.2] Replace internal phase labels with versioned capability terminology #140 — living terminology cleanup.
• [v0.2] Rebaseline AGENTS.md for WrightKit repository ownership #141 — repo-local AGENTS.md routing alignment (completed; retain as governance evidence).

Non-goals

• Production opy-rs cutover; target v0.3.
• Production del-rs cutover; target v0.4.
• New refactoring categories merely to exercise LPP.
• Implementing a third real language; conformance/mock-provider evidence is sufficient for v0.2.
• Public AST/HIR/WIR ABI.
• Compatibility expansion unrelated to the ownership migration.

Acceptance criteria

• The ownership decision is accepted and living Wright docs match it.
• language-provider-protocol and workshop-rs are real independently versioned repositories with usable contracts, not placeholders.
• LPP v1 is provider/language agnostic and has machine-testable conformance.
• workshop-rs owns canonical Workshop semantics/catalog/WIR and demonstrates the declared en-US <-> zh-CN raw Workshop conversion gate.
• Wright consumes workshop-rs without retaining a second canonical Workshop implementation.
• Wright initializes a conforming provider through its LPP client and exercises validated mutation through that boundary.
• Existing declared Wright compile/check/lint/analyze/inspect/convert/language-service behavior stays regression-green during migration.
• Active repository terminology and AGENTS.md route work to the correct repository owner.
