- Updated import rewriting to identify and publish `var` and `function` declarations to the global scope when a cell contains top-level `await`.
- Prevented these declarations from being trapped within the async wrapper's function scope, allowing them to remain accessible to subsequent evaluation cells.
- Made `JsRuntime` track the realm globals it installs (`#globalOwner`, `#ownedGlobalKeys`, `PRELUDE_GLOBAL_KEYS`) and reclaim them in `dispose()`, re-binding ownership through `#activateGlobals()` on cwd/run-scope/run; disposing an older inline/direct runtime no longer deletes a newer runtime's helper globals, and overlapping same-realm runs are serialized via `enterGlobalRun`.
- Added `WorkerCore.dispose()` (rejects pending tool calls with `ToolError` and disposes the runtime) and invoked it from `spawnInlineWorker` teardown in `context-manager.ts`.
- Updated the `js-static-import-rewrite` test to snapshot and restore any pre-existing `__omp_import__` global instead of unconditionally deleting it.
- Added `runtime-global-dispose.test.ts` covering newer-runtime global survival, older-runtime reactivation, and cross-runtime mutation rejection.
- Clarified the `runWorkerEntrypoint` comment in `cli.ts` about `parentPort` sync-prefix buffering for tab/eval workers.
- Added lazy async module loaders for @babel/parser, linkedom, puppeteer/browsers, @mozilla/readability, @xterm/headless, and mnemopi to avoid loading them during cold startup.
- Added an interactive startup splash before session construction and skipped it for resume/fork/continue, quiet mode, timing mode, or non-TTY runs.
- Updated JS import-rewrite and memory tests to match async parser loading and preloaded mnemopi modules for sync state helpers.
- Rewrote dynamic `import(...)` rewriting to emit a guarded callee that prefers `__omp_import__` and falls back to native `import` when the helper is unavailable.
- Added a shared shim constant and updated import-rewrite tests to verify routed dynamic imports work both with the injected helper and after serializing into a realm without it.
- Updated local module loading to force TS syntax stripping for .ts/.tsx/.mts modules and use the matching Bun transpiler loader.
- Extended TypeScript stripping to detect `import type`/`export type` syntax and rewired wrapping to strip TS syntax after final-expression extraction with TypeScript-aware parsing.
- Added tests verifying type-only imports are handled correctly in evaluator modules and rewritten code no longer contains type-only import declarations.
- Added guard for ASTs with no body and trimmed trailing EmptyStatement nodes before final-expression capture.
- Exposed wrapCode via context-manager export for external JS import-rewrite callers.
- Added regression test asserting final-expression wrapping when trailing semicolons follow await.
- Updated JS import rewriting to route top-level `import` declarations through `__omp_import__` with support for import attributes.
- Added AST traversal to replace `import(...)` call callee nodes with `__omp_import__` so dynamic imports resolve via session-aware helper.
- Updated runtime `__omp_import__` to accept an optional options object and pass it through to `import(target, options)`.
- Rewrote static import lowering to emit `__omp_import__` calls instead of direct `import(...)` so rewritten code routes through worker context helpers.
- Added a `__omp_import__` runtime helper in `WorkerCore` that resolves specifiers against the session cwd via `Bun.resolveSync` while passing through URL-like modules unchanged.
- Updated static import rewrite tests to expect the new helper-based `__omp_import__` form, including import attribute cases.
- Replaced regex-based import rewriting in `rewriteStaticImports` with Babel AST parsing.
- Handled default, namespace, named, and side-effect imports, preserving `import ... with` options.
- Returned original source on no top-level imports, parse failures, or unchanged non-import regions.
- Added `@babel/parser` dependency and tests/changelog coverage for top-level static-import rewrite behavior.
