Bring back per-category model selection that 5c4aa772 dropped, plus add a
new track-block category. Each is a BYOK-only override on `LlmModelConfig`
(`knowledgeGraphModel`, `meetingNotesModel`, `trackBlockModel`); signed-in
users always get the curated gateway default and never hit the on-disk
config.
Three helpers in core/models/defaults.ts — `getKgModel`,
`getTrackBlockModel`, `getMeetingNotesModel` — each check `isSignedIn`
first (fast path) and fall through to `cfg.<field> ?? cfg.model` for BYOK.
The model is now picked at the invocation site rather than via runtime
agent-name branching: each top-level `createRun` for a polling KG agent
or a track-block update passes `model: await getXxxModel()`. The `model:`
declarations on the affected agent YAMLs are dropped — they were dead
code under the per-call override. Standalone (non-run) callers
`track/routing` and `summarize_meeting` use the helpers inline.
Settings dialog and the two onboarding flows surface the two new fields
("Meeting Notes Model", "Track Block Model") next to the existing
"Knowledge Graph Model"; `repo.setConfig` persists all three per-provider.
Note: the signed-in `RowboatModelSettings` panel still has its
now-defunct kg selector; that's a UI cleanup for a later pass.

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`.

When signed in, default assistant to gpt-5.4, knowledge graph agents to
gpt-5.4-nano, inline task agent to gpt-5.4-mini, and meeting notes to
gpt-5.4. Add meetingNotesModel config field. Fix summarize_meeting to
use gateway provider when signed in.
