## Summary
Replaces the bolted-on `isTool` + `toolInputSchema` fields on
`LogicFunctionManifest` with two distinct, opt-in triggers that align
with the existing `cron` / `databaseEvent` / `httpRoute` trigger
pattern:
- **`toolTriggerSettings`** — exposes the function as an AI tool (chat /
MCP / function calling). Uses standard JSON Schema (the format LLMs
natively understand).
- **`workflowActionTriggerSettings`** — exposes the function as a step
in the visual workflow builder. Uses Twenty's rich `InputSchema` so the
builder can render proper `FieldMetadataType`-aware editors, variable
pickers, labels, and an optional `outputSchema`.
A function can opt into none, one, or both. Each surface gets the schema
format appropriate for it.
### Why
`isTool: true` previously exposed the function as both an AI tool AND a
workflow node, with the same JSON Schema feeding both — but the workflow
builder really wants Twenty's `InputSchema` (with `CURRENCY`,
`RELATION`, `EMAILS`, etc.) and the AI surface really wants standard
JSON Schema. Today the workflow builder hacks around this by treating
JSON Schema as `InputSchema`, which silently breaks for any
non-primitive field type. Splitting the triggers fixes that and lets
each surface evolve independently.
### Migration
- **Fast** instance command adds the two new nullable columns.
- **Slow** instance command backfills `toolTriggerSettings` +
`workflowActionTriggerSettings` from `isTool=true` rows (preserving
today's both-surfaces behaviour) then drops the legacy columns.
### Stacked
Stacked on top of #20181. Merge that first, then this.
## Test plan
- [ ] CI green (oxlint, typecheck, jest, vitest)
- [ ] Run `--include-slow` upgrade against a workspace with existing
`isTool=true` logic functions; verify both new columns populated and old
columns dropped
- [ ] Verify AI chat sees migrated tool functions (Linear create-issue,
Exa search) and can call them with the JSON Schema
- [ ] Add an AI-tool function from the Settings UI (toggles
`toolTriggerSettings`) and verify it shows up in chat
- [ ] Add a workflow-action function from the Settings UI (toggles
`workflowActionTriggerSettings`) and verify it appears in the workflow
node picker
- [ ] In the workflow builder, edit a `LOGIC_FUNCTION` step and verify
input fields render (no more JSON-Schema-as-InputSchema hack)
- [ ] Try defining a function with no triggers in the SDK and verify
`defineLogicFunction` rejects it
