What

Adds two CP-tier management tools that wrap the control-plane cross-cloud provider-migration endpoint, closing the capability gap (#64) where the canvas can migrate a workspace's compute box across clouds (AWS ↔ Hetzner ↔ GCP) but the management MCP could not. update_workspace exposes tier but has no provider field, so there was no path to change a workspace's compute provider through the MCP.

Tools

migrate_workspace_provider — POST /api/v1/admin/workspaces/:id/migrate-provider {from,to,confirm:true,…} → 202 {status:"migration_started"}. Data-safe + async (~15-20 min): CP snapshots the source's /workspace to R2, provisions the target (restores on boot), verifies health, then retires the source (verify-before-destroy + rollback live in CP).
get_workspace_migration_status — GET same path → {migration:{state,from_provider,to_provider,detail,…}, terminal}; 404 mapped to a clean NOT_FOUND.

Contract guards (client-side, fail-fast)

Mirrors the CP handler so a bad call surfaces a clear message instead of round-tripping a CP 400/503:

to required, provider enum aws|hetzner|gcp.
from required by CP; auto-resolved from the workspace's current provider when omitted; must differ from to.
confirm:true is mandatory — a real migration mutates two clouds. confirm defaults to false; the tool refuses without it (never auto-confirms a destructive op).
from_instance_id required for non-AWS (Hetzner/GCP) sources (no workspace→instance resolver); optional for AWS (CP resolves from EC2 tags, cp#711).

Both tools are gated on CP_ADMIN_API_TOKEN (the Org API Key cannot reach the control plane), living in cp_admin.ts alongside the existing recreate_workspace tool and following its exact pattern.

Tests

New Jest coverage (full suite green: 314 passed, 1 skipped): URL/method/body/auth-bearer, CP-tier gating, confirm-gating, from auto-resolution + FROM_UNRESOLVED, non-AWS from_instance_id requirement, from===to rejection, 404→NOT_FOUND, and CP error mapping. Registration assertion updated for the two new tool names.

Closes #64

Add two CP-tier management tools that wrap the control-plane cross-cloud
provider-migration endpoint, closing the capability gap where the canvas
can migrate a workspace's compute box across clouds (AWS <-> Hetzner <->
GCP) but the management MCP could not.

- migrate_workspace_provider: POST /api/v1/admin/workspaces/:id/migrate-provider
  {from,to,confirm:true,...} -> 202 {status:migration_started}. Resolves
  `from` from the workspace when omitted, enforces the CP contract guards
  client-side (provider enum, from!=to, confirm required, from_instance_id
  required for non-AWS sources), and never auto-confirms a destructive
  two-cloud op (confirm defaults to false).
- get_workspace_migration_status: GET same path -> {migration:{state,...},
  terminal}; maps 404 to a clean NOT_FOUND.

Both gated on CP_ADMIN_API_TOKEN (the Org API Key cannot reach the CP),
mirroring the existing recreate_workspace cp_admin tool. Jest tests cover
the URL/method/body/auth, confirm-gating, from auto-resolution, non-AWS
from_instance_id requirement, and CP error mapping.

Closes #64

APPROVED 8d44bee0. 5-axis clean: correctness adds the two CP-tier migration tools against the documented admin migrate-provider endpoint with status polling; robustness covers confirm gating, provider/from validation, non-AWS from_instance_id, 404 mapping, URL encoding, and CP error paths; security keeps the tools behind CP_ADMIN_API_TOKEN and never auto-confirms the destructive migration; performance adds only async CP calls/no blocking local work; readability and tests are clear. Note: Gitea PR diff/files endpoints returned 500, so review used local git diff against origin/main.

5-axis review on head 8d44bee0: correctness/robustness/security/performance/readability checked via local diff against origin/main because Gitea diff/files returned 500. The new handlers themselves are CP_ADMIN_API_TOKEN-gated, use the CP admin bearer for POST/GET, encode workspace_id, require confirm:true for migration, enforce provider enum/from!=to/non-AWS from_instance_id, and tests exercise the real exported handlers plus registry composition. CI is green.

Request changes: contract/documentation drift. The PR adds two public CP-tier management tools, migrate_workspace_provider and get_workspace_migration_status, but README.md still documents the CP-tier surface as only list_orgs/get_org (README.md:126, README.md:158-164) and says CP_ADMIN_API_TOKEN is required only for list_orgs/get_org (README.md:178). src/index.ts:270-272 also has the same stale comment. This makes the public management contract/auth guidance wrong for the new tools. Please update the CP-tier tool list and CP_ADMIN_API_TOKEN wording before merge.

5-axis review: APPROVED. Correctness: migrate_workspace_provider and get_workspace_migration_status are registered CP-tier tools using CP_ADMIN_API_TOKEN, encode workspace ids, enforce confirm:true, validate provider enums, require from_instance_id for non-AWS sources, and surface structured start/status errors. Security: no tenant-org-key escalation; operations are gated on CP admin bearer and status remains CP-admin scoped. Tests: management tests cover token absence, request body/auth/path, confirmation/provider guards, non-AWS source id, auto-resolved from provider, CP errors, 404 status, and registration. Robustness/performance: fail-fast validation avoids destructive bad calls; migration remains async. Readability/scope: contained to cp_admin and tests. Note: Gitea PR files/diff endpoints still 500, so I reviewed local git diff against main.
