Refactor Electron raw print IPC

[kilbot]

Summary

• Add a shared Electron renderer ipc-print.electron helper for IPC lookup, Uint8Array → number[] conversion, the 30s renderer timeout, and timer cleanup.
• Refactor serial, USB, and network Electron adapters to delegate raw ESC/POS IPC sends to the shared helper.
• Point apps/electron at the companion Electron PR commit that centralizes main-process raw-print delivery.

Design decisions (preserve through rebases)

• IPC channel names and payload shapes are unchanged — renderer adapters still call print-raw-serial / print-raw-usb with { device, data } and print-raw-tcp with { host, port, data }.
• Renderer timeout remains 30s — the main process keeps shorter transport-specific timeouts so native errors win first.
• The shared IPC lookup intentionally supports both window.ipcRenderer and window.electronAPI?.ipcRenderer, fixing the network adapter fallback gap without changing the preload contract.

Companion PRs / cross-repo

• Refactor raw print delivery electron#278 — centralizes main-process raw-print validation, timeout/cleanup, transport Delivery seams, and adds the new raw-print seam test.

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 56 minutes and 28 seconds. Learn how PR review limits work.

To continue reviewing without waiting, enable usage-based billing in the billing tab.

⌛ 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.
