* fix: specify TS_NODE_PROJECT for dev:server script
ts-node/register resolves tsconfig from the entry file upward,
finding the root solution-style tsconfig.json (no compilerOptions).
This causes target to default to ES3, breaking MapIterator spread
syntax (TS2802). Set TS_NODE_PROJECT env var to point to the server
tsconfig which targets ES2024.

* feat: add token usage tracking, context display, and dynamic context length
- Intercept SSE proxy to capture run.completed events and persist token
usage (input_tokens, output_tokens) per session to SQLite/JSON store
- Display context usage bar in ChatInput showing used/total/remaining tokens
- Resolve actual context length from Hermes models_dev_cache.json based
on the active profile's default model (fallback 200K), with 5min in-memory cache
- Move sessions-db.ts to db/hermes/ for unified database layer
- Add usage store with SQLite + JSON fallback (auto-migration via ensureTable)
- Fix proxy SSE path regex to match rewritten upstream path
- Fix route ordering: /sessions/usage before /sessions/:id to avoid 404
- Fetch per-session usage on session enter instead of batch
- Add unit tests for usage-store, db index, and proxy SSE interception

Replace static top-level import with runtime version check and dynamic
import() so Node < 22.5 gracefully falls back to CLI path instead of
crashing at module load time.

SQLite path was returning null title for sessions without an explicit
title, while the CLI path derives it from the first user message.
Now uses the preview (first user message content) as title fallback,
matching the original CLI behavior.
