feat(agents)!: write the agent core once in Tish, for JavaScript and native - #38

…native
The agent core (loop, runtime of agents, orchestration tools, profiles, supervisor, plans, stores, persistent runs,
the Hypery model call) is now Tish (tish/agents), compiled into the package with its TypeScript declarations by
`npm run build:core` (@tishlang/tish 4.2.2). Dune's cloud agents run the same source natively: the `./agents` export
has a `tish` condition pointing at it. `npm run test:tish` runs tish/agents/smoke.tish on Tish's VM and as the
shipped JavaScript and checks they agree (in CI); the same program builds and matches natively.
What JavaScript hosts add stays TypeScript: indexedDbStore, fileStore, the React hooks, the platform fetch for
createHyperyModel, and real AbortSignals for each child (createSignal → AbortController), so a child's tools can
pass ctx.signal to fetch and stopping it cancels its requests.
BREAKING CHANGE: no classes. `new AgentRuntime(host)` is `createAgentRuntime(host)`, `new TodoList(…)` is
`createTodoList(…)`, and model errors are values `{ name: "AgentModelError", message, code, status }` (check with
`isAgentModelError`, make with `agentModelError`) — `instanceof AgentModelError` no longer works. Absent values are
`null`: `runtime.get(id)` / `wait` return null for an unknown id. A host model call's `signal` is anything with
`aborted`; with a host-supplied createSignal it may be a plain flag rather than an AbortSignal.

The agent core (loop, runtime of agents, orchestration tools, profiles, supervisor, plans, stores, persistent runs, Hypery model call) is now written once in Tish in

Dune's cloud agents run it natively; this package ships it compiled to JavaScript with generated TypeScript declarations.npm run build:corecompiles it (@tishlang/tish4.2.2), thentscbuilds the TypeScript adapters around it../agentsgets atishexport condition, so Dune imports the Tish source.npm run test:tish(in CI) runstish/agents/smoke.tishon Tish's VM and as the shipped JS and checks they agree.

Promise.spawn,delay,utf8Complete,--types, and the native compiler fixes).Tests: 100 SDK tests pass (one new: a child's
