Summary

Port of Seria from Tauri 2.0 (Rust backend) to Electrobun (single-runtime Bun) per the Electrobun Port Plan. Seria becomes the first test of the single-runtime desktop pipeline, paving the way for Poppy and Lily.

Entire Rust backend (1900+ lines: file_ops, storage, screenplay converter, CSV diff) ported to TypeScript under Bun.
All 16 former Tauri commands + thin wrappers for dialog/clipboard/fs/window/path become typed RPC methods shared between main and renderer.
React/Zustand tree moved from frontend/src/ → src/mainview/ with mechanical import-path changes only; component/store logic intact.
backend/, scripts/sync-version.*, and every @tauri-apps/* dep removed.
Storage locations (~/.config/seria/ etc.) unchanged so existing preferences/configs/workspaces load without migration.
160 tests passing (renderer, Bun handlers, screenplay converter, CSV diff — including the previously-ignored All-About-Eve roundtrip).

Test plan

Automated (already green locally):

bun test — 160 pass (renderer tests + 10 handler smoke tests + 10 screenplay + 6 diff)
bunx tsc --noEmit — clean
bun build.ts — view + 3 workers bundle cleanly
bunx electrobun dev — launches, navigates to views://mainview/index.html, emits main.tsx: RPC bootstrapped + React mounted via viewLog

Manual (for smoke-testing):

Open a CSV via the native file dialog; edit, save, reopen, confirm content matches
Preferences persist across restarts (~/.config/seria/preferences.json)
Custom print save/load/delete cycle
Workspace layouts save and restore
Screenplay ↔ CSV roundtrip on the All-About-Eve sample
CSV diff UI renders expected added/deleted/modified indicators on a known-diff pair
Clipboard copy-paste on cell content
Custom titlebar minimize/maximize/close still work
PDF export writes to the chosen folder

Reassessment signals (from the port plan)

Watch for these during smoke testing — if any show up, flag before merge:

Utils.openFileDialog behaving differently on macOS/Windows vs. the Linux spike.
Release bundle materially larger than the Tauri baseline (current: 125MB unpackaged Linux bundle vs. Tauri's 79.6MB AppImage; 98MB of that is the bundled Bun runtime, in line with Electrobun's architecture).
Worker-message performance regressions on large CSVs (>100k rows).
Any screenplay-conversion edge-case differences not covered by the ported tests.
