- Session class with Symbol.asyncDispose for `await using` ergonomics (ES2024)
- forge.session({ agent }) preferred form; forge.createSession() explicit
- forge.listSessions() / forge.getSession()
- TurnResult / TurnEvent / SessionState types + turnText() helper
- Idempotent Session.close() (200 on re-close server-side)
- tests/sessions.test.ts: 13 tests covering disposal/idempotency/throw/list/state/404/regression
- README "Multi-turn / Sessions (v0.2)" section + fallback try/finally docs
tsconfig.json: lib bumped to add ES2023 + ESNext.Disposable so the
Symbol.asyncDispose / AsyncDisposable types resolve under TS 5.9. Target
stays ES2022 — the disposable runtime hooks are TS-erasable, no runtime
polyfill needed; consumers just need Node 20.4+ at runtime to use the
`await using` form (documented in the README; the v0.1 surface and the
explicit createSession + try/finally fallback continue to work on Node 18+).
package.json: bumped to 0.2.0; engines.node stays >=18 since the v0.1
surface is unchanged. v0.1 /run path unchanged (regression test added).
