fix(studio): unbreak proto loading in the deployed image

[yordis]

• The Studio production image could not start: every cross-file proto import failed to resolve because the proto include path was anchored to the server file's own location rather than to where the proto tree actually ships.
• pnpm deploy flattens the server package to sit at a different directory depth than the source tree, so an assumption that held in development silently broke once the image was built.

PR Summary

Low Risk
Small startup-path change with a contract test; wrong paths would fail at boot rather than silently misbehaving in production traffic.

Overview
Fixes Studio failing to boot in the production image when cross-file proto imports could not resolve.

PROTO_INCLUDES is no longer computed from the server module’s __dirname (which assumed the monorepo depth). It is now derived from PROTO_PATH: four parent segments above service.proto, which lands on the proto tree root in both dev and the deployed layout where server/ and proto/ are siblings under /app.

A contract test simulates that pnpm deploy directory shape and asserts EventModelService still loads with the same include-dir rule as index.mjs.

Walkthrough

The server now derives its proto include directory from PROTO_PATH. A contract test checks the resolution in a deployed layout and verifies that the service constructor loads.

Changes

Proto include path resolution

Layer / File(s)	Summary
Resolve and verify proto include directory tsworkspace/webapps/studio/server/index.mjs, tsworkspace/webapps/studio/server/devops-contract.test.mjs	PROTO_INCLUDES now resolves four levels above the directory containing PROTO_PATH. The contract test checks that it points to the sibling proto directory and that service.proto exposes EventModelService.

Change: Bug fix

Merge Risk: 🔵 Low · up to da81b

The deployed proto path currently resolves correctly, but the contract test would not catch a regression in the server’s include-path configuration. The change is mergeable with this test gap addressed as a follow-up.

Test the server’s configured include path.

The deployed-layout test supplies its own includeDir to loadServiceCtor. It does not exercise server/index.mjs or PROTO_INCLUDES, so reverting the server-relative calculation can leave this test passing.
