fix(ashby): fail loudly instead of silently dropping malformed socialLinks

parseSocialLinksInput returned [] for any non-JSON-parseable input, and
tools.config.params only sets result.socialLinks when the parsed array is
non-empty — so a malformed socialLinks string (user typo, or a wand
response that didn't follow the JSON-array prompt) silently omitted the
field entirely. The Ashby candidate.update call then succeeded without
applying the requested links, with no error surfaced to the workflow
author. Throw a clear error instead, matching the existing
throw-on-invalid-JSON pattern used elsewhere (e.g. blocks/airtable.ts).
