Add typed Electron IPC channel registry

[kilbot]

Summary

• Adds a pure @wcpos/printer/ipc-channels registry for Stage 1 Electron IPC channel names and request/response types.
• Retypes the printer Electron renderer adapters/hooks against TypedIpcRenderer so wrong Stage 1 channel names or payload shapes fail at compile time.
• Updates the Electron submodule pointer to the companion branch that derives preload allowlists and Stage 1 main handlers from the registry.
• Removes the dead rxStorage invoke channel from the typed/preload invoke set while preserving the dynamic RxDB channel prefix path.

Design decisions (preserve through rebases)

• Option A registry import — the registry is authored as .cts so preload can import runtime constants from @wcpos/printer/ipc-channels under the existing plain ts-node preload test.
• Legacy TS resolution shim — packages/printer/ipc-channels.d.ts keeps Node10-style TypeScript resolution working for packages that import the new subpath directly.
• No runtime channel renames — existing string literals are centralized byte-for-byte; Stage 1 migration covers print/discovery only.
• rxStorage removed intentionally — the live RxDB bridge uses dynamic rxdb-ipc-renderer-storage|<key> channels, and the only rxStorage handler is in an uncompiled .bak file.

Companion PRs / cross-repo

• Derive print IPC channels from typed registry electron#281 — consumes the registry in preload and Stage 1 print/discovery main handlers; required by the submodule pointer in this PR.

Test plan

• Run pnpm --filter @wcpos/app-electron ts:check from this monorepo worktree.
• Run pnpm --filter @wcpos/app-electron lint and confirm there are 0 errors (warnings are pre-existing require/no-unused warnings).
• Run pnpm --filter @wcpos/app-electron test.
• Run targeted Electron scripts: test:preload, test:printer-discovery, test:serial-printer, test:winspool-printer.
• Run pnpm --filter @wcpos/printer exec tsc --noEmit -p tsconfig.json.
• Run pnpm --filter @wcpos/printer exec vitest run.
• Negative type-safety proof: temporarily change a renderer call to a bad channel (for example print-raw-usbZZ), confirm printer tsc --noEmit fails, then revert before merging.

Known blockers

• Merge the companion Electron PR before or together with this PR so the submodule pointer resolves cleanly.

Warning

Review limit reached

@kilbot, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 52 minutes and 2 seconds. Learn how PR review limits work.

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

Add state to the auth prompt request type

The existing Electron auth caller sends state in the auth:prompt payload for CSRF validation (packages/core/src/hooks/use-wcpos-auth/index.electron.ts:72-75), but this new source-of-truth request type only permits authUrl and redirectUri. When the registry is used to type this channel, the current payload is rejected by excess-property checks or typed code is forced to omit state, which can break auth flows that rely on main-process state validation.
