feat: inline node execution for FBP native nodes in compute worker

[pyramation]

Summary

FBP native nodes (number, add, multiply, select, object, guard, template, concat, string, boolean) now execute in-process in the compute worker instead of failing on HTTP dispatch.

Previously, tick_execution dispatched ALL non-boundary nodes as jobs to app_jobs.jobs. The worker tried to POST every job to a function URL — but native nodes have no HTTP endpoint, so they'd fail. Now both paths converge:

tick_execution → app_jobs.jobs → Worker.doWork
                                   ├─ inline registry hit? → impl(inputs, props) → complete_node SQL
                                   └─ no match?            → HTTP POST → fn-app → callback

Key design decision: The inline path calls the same platform_complete_node / platform_fail_node SQL as cloud functions. The graph engine sees no difference between inline and HTTP invocations — same state transitions, same output storage, same tick_execution re-entry.

New files

• job/worker/src/inline-nodes.ts — INLINE_NODES registry mapping task identifiers to NodeImplFn, plus isGraphJob() and extractNodeProps() payload helpers. Implementations match @fbp/evaluator definitions (same (inputs, props) => outputs contract).

• job/worker/src/graph-complete.ts — completeNode(pool, executionId, nodeName, output) and failNode(pool, executionId, nodeName, message) — thin wrappers that call the constructive_compute_private SQL procedures.

Modified

• job/worker/src/index.ts — Worker.doWork checks getInlineImpl(task_identifier) + isGraphJob(payload) before falling through to HTTP dispatch. On error, calls failNode instead of letting the job fail at the queue level.

Tests

32 new tests across two files:

• tests/integration/inline-nodes.test.ts — registry completeness, all 11 node impls, isGraphJob, extractNodeProps, completeNode/failNode SQL mock verification
• tests/integration/inline-worker.test.ts — Worker.doWork integration: inline execution → complete_node SQL, props extraction, HTTP fallback for cloud functions, fail_node on impl error, async impl support
