[Export] Bulk-mode results are all strings — same query exports different JSON types than REST mode #80

Severity

Low.

What happens

Bulk query results are parsed with Papa without dynamicTyping, yielding string-only records; REST mode yields typed JSON. The same query exported as JSON gives "AnnualRevenue": 500000 via REST but "AnnualRevenue": "500000" via Bulk (booleans likewise "true"), and Bulk cannot distinguish null from empty string.

Evidence

• src/services/salesforce/bulk-api.ts:243-258

Suggested fix

Coerce obvious numerics/booleans when parsing bulk CSV pages, or document/normalize the difference.
