[Bug] Workflow dispatch by scriptPath drops args; user-global ~/.claude/workflows/ not resolvable by name

Bug Description
---Title: Dynamic Workflow: scriptPath dispatch drops args; user-global ~/.claude/workflows/ not resolvable by name

Body: Two issues building a reusable dynamic workflow (research preview, v2.1.154+):

1. Workflow({ scriptPath, args }) runs the script but the args global is empty/undefined. Workflow({ name, args }) passes

args fine. Expected: args passed regardless of dispatch mode.

1. Workflow({ name: 'x' }) returns "not found" for a workflow at ~/.claude/workflows/x.mjs (user-global), while a

plugin-shipped workflow (deep-research) resolves by name. Docs imply ~/.claude/workflows/ resolves with project-precedence —
possibly symlinks aren't scanned, or a raw .mjs needs registering via /workflows save.

Use case: dispatching one workflow as an autonomous engine across many host repos, with per-run config. Currently neither
mode gives global-findable and args.
