Nicholas Tindle 47a3a5ef41 feat(backend,frontend): optional credentials flag for blocks at agent level (#11716)
This feature allows agent makers to mark credential fields as optional.
When credentials are not configured for an optional block, the block
will be skipped during execution rather than causing a validation error.

**Use case:** An agent with multiple notification channels (Discord,
Twilio, Slack) where the user only needs to configure one - unconfigured
channels are simply skipped.

### Changes 🏗️

#### Backend

**Data Model Changes:**
- `backend/data/graph.py`: Added `credentials_optional` property to
`Node` model that reads from node metadata
- `backend/data/execution.py`: Added `nodes_to_skip` field to
`GraphExecutionEntry` model to track nodes that should be skipped

**Validation Changes:**
- `backend/executor/utils.py`:
- Updated `_validate_node_input_credentials()` to return a tuple of
`(credential_errors, nodes_to_skip)`
- Nodes with `credentials_optional=True` and missing credentials are
added to `nodes_to_skip` instead of raising validation errors
- Updated `validate_graph_with_credentials()` to propagate
`nodes_to_skip` set
- Updated `validate_and_construct_node_execution_input()` to return
`nodes_to_skip`
- Updated `add_graph_execution()` to pass `nodes_to_skip` to execution
entry

**Execution Changes:**
- `backend/executor/manager.py`:
  - Added skip logic in `_on_graph_execution()` dispatch loop
- When a node is in `nodes_to_skip`, it is marked as `COMPLETED` without
execution
  - No outputs are produced, so downstream nodes won't trigger

#### Frontend

**Node Store:**
- `frontend/src/app/(platform)/build/stores/nodeStore.ts`:
- Added `credentials_optional` to node metadata serialization in
`convertCustomNodeToBackendNode()`
- Added `getCredentialsOptional()` and `setCredentialsOptional()` helper
methods

**Credential Field Component:**
-
`frontend/src/components/renderers/input-renderer/fields/CredentialField/CredentialField.tsx`:
  - Added "Optional - skip block if not configured" switch toggle
  - Switch controls the `credentials_optional` metadata flag
  - Placeholder text updates based on optional state

**Credential Field Hook:**
-
`frontend/src/components/renderers/input-renderer/fields/CredentialField/useCredentialField.ts`:
  - Added `disableAutoSelect` parameter
- When credentials are optional, auto-selection of credentials is
disabled

**Feature Flags:**
- `frontend/src/services/feature-flags/use-get-flag.ts`: Minor refactor
(condition ordering)

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
- [x] Build an agent using smart decision maker and down stream blocks
to test this

<!-- CURSOR_SUMMARY -->

> [!NOTE]
> Introduces optional credentials across graph execution and UI,
allowing nodes to be skipped (no outputs, no downstream triggers) when
their credentials are not configured.
> 
> - Backend
> - Adds `Node.credentials_optional` (from node `metadata`) and computes
required credential fields in `Graph.credentials_input_schema` based on
usage.
> - Validates credentials with `_validate_node_input_credentials` →
returns `(errors, nodes_to_skip)`; plumbs `nodes_to_skip` through
`validate_graph_with_credentials`,
`_construct_starting_node_execution_input`,
`validate_and_construct_node_execution_input`, and `add_graph_execution`
into `GraphExecutionEntry`.
> - Executor: dispatch loop skips nodes in `nodes_to_skip` (marks
`COMPLETED`); `execute_node`/`on_node_execution` accept `nodes_to_skip`;
`SmartDecisionMakerBlock.run` filters tool functions whose
`_sink_node_id` is in `nodes_to_skip` and errors only if all tools are
filtered.
> - Models: `GraphExecutionEntry` gains `nodes_to_skip` field. Tests and
snapshots updated accordingly.
> 
> - Frontend
> - Builder: credential field uses `custom/credential_field` with an
"Optional – skip block if not configured" toggle; `nodeStore` persists
`credentials_optional` and history; UI hides optional toggle in run
dialogs.
> - Run dialogs: compute required credentials from
`credentials_input_schema.required`; allow selecting "None"; avoid
auto-select for optional; filter out incomplete creds before execute.
>   - Minor schema/UI wiring updates (`uiSchema`, form context flags).
