Prerelease Alpha 29 — Spotlight crash fix & smaller bundles

Spotlight stops falling over on attached files. The renderer crash in Send-to-Rush came from a missing fileIcon.get(extension) bridge in the spotlight preload. Alpha 29 mirrors the IPC stub, so Spotlight can mount its React tree instead of dying on the first attachment chip.

The bundle is quieter and safer. This release also strips .map files from the shipped app.asar. That removes a large amount of original source structure from production builds and trims the DMG size along the way.

The result is less drama on first use. Attach a file, open Spotlight, keep moving. No cryptic React boundary crash; no oversized production bundle carrying debug baggage it should not carry.
