Adds `ai` to sqlc's `gen.go.initialisms` in `coderd/database/sqlc.yaml`
so the generated DB code follows Go's initialism convention. Adds the
matching `ai` -> `AI` case to the dbgen PascalCase helper
(`scripts/dbgen/main.go`) so the corresponding `dbmem` / mock
identifiers stay in sync. `make gen` regenerates the rest; hand-written
call sites that consume DB-generated identifiers
(`enterprise/audit/table.go`, `coderd/database/modelmethods.go`,
`enterprise/coderd/aigatewaykeys.go`, `coderd/database/dbauthz/*`, etc.)
are updated to match.
Scope is deliberately limited to the database layer:
- `coderd/rbac/*` (resource and scope generators) is untouched —
`ResourceAi*` / `ScopeAi*` constants stay on main's casing.
- `codersdk/*` (Go SDK) is untouched — `codersdk.ResourceAi*` /
`codersdk.APIKeyScopeAi*` constants stay on main's casing, so external
Go SDK consumers see no source-level break.
- `Aibridge*` identifiers (one SQL token `aibridge`, not `ai_bridge`)
are out of scope.
On-the-wire values are unchanged: enum strings, RBAC resource type
strings, API key scope strings, and JSON tags all stay the same. The
HTTP/JSON surface is unaffected.

## Summary
- Updates Coder's pinned `github.com/coder/fantasy` fork to include
coder/fantasy#39.
- Exposes Anthropic `thinking_display` as a typed chat model provider
option with `summarized` and `omitted` values.
- Validates configured `thinking_display` values and maps them to
`fantasyanthropic.ProviderOptions.ThinkingDisplay`.
- Regenerates the API/UI option schemas so the admin model config form
gets a generated select field.
## Tests
- `go mod tidy`
- `make gen`
- `go test ./codersdk ./coderd/x/chatd/chatprovider ./coderd -run
'TestChatModelProviderOptions|TestAnthropicThinkingDisplayFromChat|TestProviderOptionsFromChatModelConfig_AnthropicThinkingDisplay|TestMergeMissingProviderOptions_AnthropicThinkingDisplay|TestValidateChatModelProviderOptions_AnthropicThinkingDisplay'`
- `go test ./coderd/x/chatd/... ./codersdk`
- `go test ./coderd -run

- `pnpm --dir site exec -- biome lint --error-on-warnings

> Mux working on behalf of Mike.
OpenAI-compatible gateway providers such as OpenRouter require
slash-namespaced model IDs to reach the intended upstream model, but
native OpenAI routing strips those prefixes.
Preserve full model IDs for gateway provider types, reject
OpenRouter-like providers configured as native `openai` when a slash
model would be stripped, and validate chat model config changes under
the provider reference lock while still allowing unrelated edits to
existing configs.
Split from #26005.
> Mux created this PR on behalf of Mike.
When the chat `start_workspace` tool triggers an active-version upgrade
that introduces new required parameters, the build fails with a
parameter validation error. Previously this returned a message telling
the user to update from the UI — a dead end for the model.
This PR lets the model recover inside the chat by:
1. Accepting an optional `parameters` map on `start_workspace` (same
schema as `create_workspace`), forwarded as `RichParameterValues`.
2. Returning structured JSON error responses that preserve validation
details and the workspace's `template_id`, so the model can call
`read_template` to discover what changed.
3. Replacing the UI-only guidance in `exp_chats.go` with
model-actionable retry instructions.
The expected model flow on an active-version parameter failure is now:
```
start_workspace → fails (structured error with template_id + validations)
read_template → discovers new required parameters
start_workspace → retries with parameters map → workspace starts
```
