Error toasts are sticky (duration: 0) so a misbehaving command that fires
errors in a loop — a backend that flaps, a polling effect over a broken
endpoint — accumulates toast items in the in-memory store indefinitely.
The audit found no other unbounded $state arrays in the frontend stores
(history caps at 500, recentNudges prunes by time, tasks/taskLists
replace-on-load), but `items.push(toast)` had no upper bound.
Add MAX_TOASTS = 50 with FIFO eviction. Doesn't change behaviour for
realistic toast volumes; only kicks in if something is genuinely wrong.

Wholesale JS -> TS migration of the frontend — stores, utils, actions,
and all Svelte component scripts adopt type annotations. Compile-time
surfaces (app.d.ts, lib/types/) added for shared DTO types.
Build plumbing:
- package.json: dev:frontend script that runs svelte-kit sync first
- tauri.conf.json: beforeDevCommand points at dev:frontend
- run.sh: dropped the sed-hack that temporarily blanked beforeDevCommand;
now relies on npm run dev:frontend to avoid double-Vite
- jsconfig.json: allowImportingTsExtensions
Preserves all Group 1 behaviour:
- page.svelte.ts keeps loadHistory / loadTasks Tauri-first, no
localStorage; saveTranscriptMeta + mapTranscriptRow + mapTaskRow
intact; update_task_cmd and update_transcript_meta_cmd invocations
carry the correct payload shape.
- Toasts, preferences stores typed without behaviour change.
- Viewer still routes segment edits through saveTranscriptMeta; the
Task 1.5 TODO markers are gone.
taskExtractor.ts is functionally improved during the migration:
- multi-task matches in the same sentence
- list-style shopping-verb expansion (get bread, milk, and cheese)
