Golem improvements / fixes

• CLI MoonBit support: New agent_id_display module with MoonBit parsing/rendering
• MoonBit SDK overrides

---

Changes to SDKs

MoonBit SDK (~130 files)

• SDK tools updated to latest MoonBit
• New SDK modules: filesystem, ffi, http, api/retry, rpc, agent guest/snapshot exports
• WIT bindings: Extensive new/updated bindings across:
  • golem/agent, golem/api/oplog, golem/api/retry, golem/quota
  • golem/rdbms/* (ignite2, mysql, postgres, types)
  • wasi/filesystem/*, wasi/http/*, wasi/keyvalue/*, wasi/blobstore/*
  • and more

Scala SDK (33 files)

• Cancelable scheduled invocations — new CancellationToken type + scheduleCancelableAt codegen
• PrincipalConverter rewrite — hand-written JSON replacing derived JsonCodecDeriver
• RDBMS numeric type fixes — number vs bigint handling for unsigned ints, oid, ordinal, and execute() returns
• GolemPlugin simplification — removed unnecessary stale-linker-output detection
• Build/config — .jvmopts, cross-build test alias fix

TypeScript SDK (3 files)

• Cancelable scheduled invocations
• Principal serialization aligned wit the other SDKs (it was broken due to bigint json serialization)

---

CI

• The skill testing is now a daily job because it's too expensive to run it more frequently
• It merges the reports and uploads a HTML report to the benchmark-results repo

Merging this with two IT failures that look like the known flaky issues, being investigated separately (so the coding agent test runs can begin)
