feat: add @wolfstar/plugin-subcommands-advanced

[RedStar071]

Summary

Adds @wolfstar/plugin-subcommands-advanced, adapted from @kaname-png/plugin-subcommands-advanced for @wolfstar/http-framework.

Slash subcommands (and groups) can live in separate command classes instead of methods on a single parent class.

API

• Subcommand — parent chat-input command
• Command — child with registerSubCommand / registerSubcommandInGroup options
• @RegisterAsSubcommand / @RegisterAsSubcommandGroup — class decorators
• @wolfstar/plugin-subcommands-advanced/register — installs a CommandLoaderStrategy that wires children onto the parent after pieces are constructed

Build tooling

• Shared scripts/tsdown.config.ts (same pattern as stars-components)
• Both packages build with tsdown → dist/esm/
• tsconfig.build.json for declaration emit used by tsdown

Testing / tooling

• Integration tests via @wolfstar/http-framework-test-utils
• Vitest pinned to Vite 6 so experimental decorators still transform through esbuild

Test plan

• pnpm build (both packages via shared tsdown config)
• pnpm typecheck
• pnpm test (24 tests)
• pnpm lint

Confidence Score: 3/5

The PR is not yet clearly safe to merge because preservation of framework-native subcommand handler mappings remains unverified.

The rebuilt resolver relies on recovering non-enumerable handler-link symbols from toJSON() output, but the available implementation evidence does not establish that serialization retains those symbols or that null links remain routable.
