fix(stack): detect copied ordinary-folder identities

[jgoux]

Summary

• reject copied ordinary-folder identity markers before managed stack discovery or mutation can reuse another live folder's stack document
• centralize the check in the manager across discover, ensure, read, and start flows
• preserve legitimate ordinary-folder moves and Git identity precedence

Why

Copying an ordinary project also copies .supabase/identity.json. While both folders exist, they can otherwise present the same environment identity and resolve to the same managed stack document.

The manager now joins filesystem identity with healthy persisted stack documents and returns an actionable InvalidManagedIdentityError when another live canonical folder contains the same marker. Users are told to delete the copied marker so a new identity can be generated.

Reviewer context

This is stacked on #6218 and targets its head branch.

Automated review loop cap: this round fixed the demonstrated stop race and supervisor fixture races, removed the overfitted live-Git exception, replied to every thread, and all CI checks are green. I am not adding more defensive code for the newly proposed pre-publication ownership window without an executed repro: before publication there is no distinct persisted workspace evidence, and closing it requires a broader startup/control protocol design. The repeated live-Git suggestion is intentionally rejected because CLI-2203 explicitly gives Git identity precedence. Requesting human review on the resulting simpler design.
