chore: isolate gRPC proto file preparation behind IPC boundary

[jackkav]

Purpose

Isolate gRPC proto temp-file creation behind the Electron preload boundary, removing fs, os, and path ownership from the renderer-reachable code path as part of the nodeIntegration: false migration.

Single feature scope

Preparing proto directories and temp proto files for gRPC request execution.

Implementation notes

• Moves proto temp-file creation behind a main-process IPC boundary.
• Keeps request assembly in the renderer.
• Avoids mixing in generic request execution, OAuth, or response archival work.

Files in scope

• packages/insomnia/src/network/grpc/write-proto-file.ts
• packages/insomnia/src/main/ipc/grpc.ts
• packages/insomnia/src/main/ipc/electron.ts
• packages/insomnia/src/entry.preload.ts
• packages/insomnia/src/ui/components/modals/proto-files-modal.tsx
• packages/insomnia/src/main/ipc/__tests__/grpc.test.ts
• packages/insomnia/config/renderer-node-import-baseline.json

Baseline entries removed

• src/network/grpc/proto-directory-loader.tsx -> fs
• src/network/grpc/proto-directory-loader.tsx -> path
• src/network/grpc/write-proto-file.ts -> fs
• src/network/grpc/write-proto-file.ts -> os
• src/network/grpc/write-proto-file.ts -> path

Test automation plan

• Keeps existing focused coverage for proto file writing.
• Adds IPC contract coverage for the new grpc.writeProtoFile bridge.
• Leaves broader gRPC execution behavior unchanged.

New preload or IPC surface added

• grpc.writeProtoFile(protoFileId: string) exposed on window.main.grpc

Deliberate deferrals

• OAuth token helpers
• Generic network file IO
• Response archival helpers

Pull request overview

This PR continues the nodeIntegration: false migration by moving gRPC proto temp-file creation out of renderer-reachable code and behind the Electron IPC/preload boundary.

Changes:

• Adds a new IPC handler (grpc.writeProtoFile) in the main process to resolve a proto file by id and write it to the temp proto tree.
• Exposes window.main.grpc.writeProtoFile(protoFileId) from preload.
• Updates the proto import modal to call the new IPC method and removes renderer-node-import baseline entries for the prior direct Node builtin usage.

File	Description
packages/insomnia/src/ui/components/modals/proto-files-modal.tsx	Switches proto directory import validation path to call window.main.grpc.writeProtoFile instead of direct temp-file writing.
packages/insomnia/src/main/ipc/grpc.ts	Adds writeProtoFileById and registers the grpc.writeProtoFile IPC handler.
packages/insomnia/src/main/ipc/electron.ts	Extends the allowed IPC handle channel union with grpc.writeProtoFile.
packages/insomnia/src/entry.preload.ts	Exposes grpc.writeProtoFile on the preload bridge.
packages/insomnia/src/main/ipc/tests/grpc.test.ts	Adds unit coverage for writeProtoFileById.
packages/insomnia/config/renderer-node-import-baseline.json	Removes baseline entries for renderer Node builtin imports that are no longer needed.

• The loop is still intended to validate imported proto files (comment + error message say “could not be parsed”), but the new call to window.main.grpc.writeProtoFile(protoFile._id) only writes the temp file and won’t fail for invalid proto syntax/import resolution. This makes invalid .proto files slip through without rollback. Consider validating via an IPC path that actually parses (e.g. invoke window.main.grpc.loadMethods(protoFile._id) and ignore the result, or extend the new IPC handler to parse after writing and throw on parse errors) and update the comment/message accordingly.

      // Try parse all loaded proto files to make sure they are valid
      const loadedEntities = await db.getWithDescendants(createdDir);
      const loadedFiles = loadedEntities.filter(isProtoFile);

      for (const protoFile of loadedFiles) {
        try {
          await window.main.grpc.writeProtoFile(protoFile._id);
        } catch (error) {
          showError({
            title: 'Invalid Proto File',
            message: `The file ${protoFile.name} could not be parsed`,
            error,
