feat: add JSON and NDJSON input/output format support#118
Merged
Conversation
- Add InputFormat and OutputFormat enums (csv, json, ndjson) - Add -I/--input-format and -O/--output-format flags; --json alias preserved - Add loadJsonArray: reads full JSON array from stdin, inserts into SQLite - Add loadNdjsonInput: streams NDJSON line-by-line into SQLite - Add bindJsonValue: maps std.json.Value variants to SQLite bind calls - Add insertRowFromJson: binds a JSON object row by column name - Add printNdjsonRow: writes one NDJSON object per result row - Add printJsonRow/printNdjsonRow output path in execQuery - Use SQLITE_STATIC for all string bindings; deferred_allocs tracks serialized array/object strings so they outlive sqlite3_step - Add 14 integration tests (48-61) covering JSON/NDJSON roundtrips, null values, nested objects, empty arrays, --columns, error paths

type:feature
…ules Move @cImport to src/c.zig so all modules share a single opaque sqlite3 type. Extract bindJsonValue, insertRowFromJson, readLine, loadJsonArray, loadNdjsonInput, writeJsonString, printJsonRow and printNdjsonRow from main.zig into src/json.zig. Fix ziglint violations in json.zig (Z023, Z017, Z026).
