Add a first-class Kotoba guest tree that compiles .kotoba to wasm with Kotoba 0.7.2. v1 is AdbcStatusCode plus a packed error and a mock connection fixture. Kotoba cannot FFI libadbc; the host owns drivers. Co-authored-by: Jun Kawasaki <04.feasts_minded@icloud.com>

Add a first-class Kotoba guest binding next to the existing language trees.
What this is
Kotoba cannot FFI
libadbc. v1 is a small in-language ADBC surface:AdbcStatusCodevalues fromadbc.hstatus * 100000 + vendor_code)The host owns drivers and maps a URI to an integer kind before calling into the wasm guest.
How it is built
.kotobasource compiles to wasm with Kotoba 0.7.2. Fixtures exportmainand return0on success.Kotoba CI on the fork is green: https://github.com/kotoba-lang/arrow-adbc/actions/workflows/kotoba.yml
Fork review: kotoba-lang#1
An ASF ICLA may be required before this can be accepted. Happy to file a JIRA/GitHub issue first if maintainers want that.
Test plan
