feat: full feature parity for all 42 SDKs + comprehensive tests

All SDKs now implement 58+ functions matching C reference (un.h):
- Execution (8): execute, execute_async, wait_job, get_job, cancel_job, list_jobs, get_languages, detect_language
- Sessions (9): list, get, create, destroy, freeze, unfreeze, boost, unboost, execute
- Services (17): list, get, create, destroy, freeze, unfreeze, lock, unlock, set_unfreeze_on_demand, redeploy, logs, execute, env_get/set/delete/export, resize
- Snapshots (9): list, get, session, service, restore, delete, lock, unlock, clone
- Images (13): list, get, publish, delete, lock, unlock, set_visibility, grant/revoke_access, list_trusted, transfer, spawn, clone
- PaaS Logs (2): fetch, stream
- Utilities (5): validate_keys, hmac_sign, health_check, version, last_error

Test suites created for all SDKs with unit, integration, and functional tests.

Languages: AWK, Bash, C++, C#, Clojure, COBOL, Crystal, D, Dart, .NET, Elixir, Erlang, F#, Forth, Fortran, Go, Groovy, Haskell, Java, JavaScript, Julia, Kotlin, Lisp, Lua, Nim, Objective-C, OCaml, Perl, PHP, PowerShell, Prolog, Python, R, Raku, Ruby, Rust, Scheme, Swift, Tcl, TypeScript, V, Zig
