refactor(ipc): split lib/ipc.ts into domain modules behind a barrel

[appergb]

User description

Summary

First of the #697 god-file splits. Pure, behavior-preserving reorganization of src/lib/ipc.ts (1765 lines, ~118 public exports) into a src/lib/ipc/ folder of 22 domain modules behind a barrel index.ts.

• All original exports re-exported from the barrel → every consumer import … from '…/lib/ipc' resolves unchanged (0 consumer edits; 33 import sites verified).
• Domains: dictation, asr-credentials, polish/settings, history, vocab, style-packs, hotkeys, permissions, devices, qa, less-computer, updater, remote-server, coding-agent, marketplace (+cache), github-oauth, plus shared invokeOrMock/Tauri helpers, mock-data, utils.
• No logic/signature/name changes. Repo convention ("all backend calls go through lib/ipc") preserved — the barrel is lib/ipc.

Verification

• export-name diff old→new: nothing dropped (118 old names all present).
• npx tsc --noEmit: clean. npm run build: clean.

Part of #697 (split oversized modules). Frontend-only; no Rust/cfg changes.

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis 🔶 697 - Partially compliant Compliant requirements: Splits the file into domain modules under src/lib/ipc/ with a barrel index.ts. Behavior-preserving: no logic changes, all exports preserved (verified by export-name diff). All original exports are re-exported from barrel; consumer imports unchanged (verified with 33 import sites). Passes tsc --noEmit and npm run build (verified in PR description). Non-compliant requirements: (Not applicable) The ticket mentions "pass cargo test (446)" but this PR only affects frontend TypeScript code; no Rust changes. Requires further human verification: All-platform CI results (e.g., Windows, macOS, Android) are not yet visible; human verification of CI status is needed.
