* fix(import): auto-detect JSON format and show readable errors (#1)
Readable import errors, a fail-soft v4 parser, and auto-detect of the JSON format so uploads just work. The format dropdown becomes an optional override. PDF and DOCX (AI) paths are untouched.
* fix(import): address review feedback on the v4 guard and error message
- reactive-resume-v4-json.tsx: reject arrays in isRecord so array-valued
basics, sections, or metadata no longer pass the v4 shape guard.
- reactive-resume-v4-json.tsx: reuse the guard's error instance in the
catch arm instead of allocating a duplicate NOT_V4_MESSAGE.
- error.ts: use a singular "Problem" label for root-level Zod issues so
the message stays grammatical.
- add a regression test for array-valued v4 branches.
* fix(import): preserve selected JSON format
* test(import): cover selected JSON parser
