Add generic agent reflection and TypeScript clients

[noise64]

• resolves GOL-44
• resolves GOL-45
• hardens reflected lifecycle creation by draining owned handles on recoverable failures and requiring agent view permission for full-ID lookup
• moves generic schema renderers into golem-schema while retaining platform renderers in golem-common
• replaces the TypeScript clientFor(...) helper with definition-owned .client factories (get, getPhantom, and newPhantom), and adds caller-owned AgentId.client(...) plus schema-native AgentId.dynamicClient() across the SDK, bridge, REPL, templates, tests, skills, and docs
• completes TypeScript environment-scoped identity, immutable shared graph decoding, strict lookup documentation, output validation, and integer boundary behavior
• restores strict reusable UTF-8 decoding for blobstore and key-value payloads
• adds the language-neutral golem-agent-reflection skill, renames the TypeScript reflection skill, and regenerates skill documentation
• synchronizes mirrored WIT and generated TypeScript/Scala declarations after the main rebase

Verification

• cargo build -p golem
• cargo fmt --all -- --check
• golem-schema renderer tests: 3 passed
• golem-common renderer tests: 100 passed
• worker-executor lifecycle cleanup and typed worker failure category tests: passed
• TypeScript workspace build and tests: 826 passed, 20 skipped
• TypeScript lint and formatting checks
• TypeScript agent-template build with a 4 GB Node heap
• reflection scenario harness dry-run
• WIT and documentation drift checks
