Ramnique Singh 5c4aa77255 freeze model + provider per run at creation time
The model dropdown was broken in two ways: it wrote to ~/.rowboat/config/models.json
(the BYOK creds file, stamped with a fake `flavor: 'openrouter'` to satisfy zod
when signed in), and the runtime ignored that write entirely for signed-in users
because `streamAgent` hard-coded `gpt-5.4`. Model selection was also globally
scoped, so every chat shared one brain.

This change moves model + provider out of the global config and onto the run
itself, resolved once at runs:create and frozen for the run's lifetime.

## Resolution

`runsCore.createRun` resolves per-field, falling through:

  run.model    = opts.model    ?? agent.model    ?? defaults.model
  run.provider = opts.provider ?? agent.provider ?? defaults.provider

A new `core/models/defaults.ts` is the only place in the codebase that branches
on signed-in state. `getDefaultModelAndProvider()` returns name strings;
`resolveProviderConfig(name)` does the name → full LlmProvider lookup at
runtime. `createProvider` learns about `flavor: 'rowboat'` so the gateway is
just another flavor.

`provider` is stored as a name (e.g. `"rowboat"`, `"openai"`), not a full
LlmProvider object. API keys never get written into the JSONL log; rotating a
key in models.json applies to existing runs without re-creation. Cost: deleting
a provider from settings breaks runs that referenced it (clear error surfaced
via `resolveProviderConfig`).

## Runtime

`streamAgent` no longer resolves anything — it reads `state.runModel` /
`state.runProvider`, looks up the provider config, instantiates. Subflows
inherit the parent run's pair, so KG / inline-task subagents run on whatever
the main run resolved to at creation. The `knowledgeGraphAgents` array,
`isKgAgent`, and the per-agent default constants are gone.

KG / inline-task / pre-built agents declare their preferred model in YAML
frontmatter (claude-haiku-4.5 / claude-sonnet-4.6) — used at resolution time
when those agents are themselves the top-level agent of a run (background
triggers, scheduled tasks, etc.).

## Standalone callers

Non-run LLM call sites (summarize_meeting, track/routing, builtin-tools
parseFile) and `agent-schedule/runner` were branching on signed-in
independently. They all route through `getDefaultModelAndProvider` +
`resolveProviderConfig` + `createProvider` now; `agent-schedule/runner`
switched from raw `runsRepo.create` to `runsCore.createRun` so resolution
applies to scheduled-agent runs too.

## UI

`chat-input-with-mentions` stops calling `models:saveConfig`. The dropdown
notifies the parent via `onSelectedModelChange` ({provider, model} as names);
App.tsx stashes selection per-tab and passes it to the next `runs:create`.
When a run already exists, the input fetches it and renders a static label —
model can't change mid-run.

## Legacy runs

A lenient zod schema in `repo.ts` (`StartEvent.extend(...optional)` plus
`RunEvent.or(LegacyStartEvent)`) parses pre-existing runs. `repo.fetch` fills
missing model/provider from current defaults and returns the strict canonical
`Run` type. No file-rewriting migration; no impact on the canonical schema in
`@x/shared`.
