zeekay e72df52f3d state: decode wrapped YAML manifests; reject unwrapped

The on-disk plugin manifest format wraps every definition in a single
top-level key (`vm:` for VMs, `subnet:` for chains). The previous
yaml.Unmarshal into a bare T silently returned a zero-valued definition
when the wrapper was present (every shipped manifest), causing
`install-vm cevm-darwin-arm64` to crash on a nil URL.

Add decodeWrapped[T] that:
  - parses to yaml.Node
  - asserts a single top-level mapping containing the expected key
  - unmarshals only the value below that key into T

Unwrapped manifests are now rejected with a clear error rather than
producing a silent zero T.

Tests cover wrapped vm, wrapped chain, missing-key rejection, and
empty-input rejection. CI-PREMORTEM.md §12a in luxcpp/cevm has the
full root-cause writeup.

Also:
  - .gitignore: ignore bin/ (was leaking 15M lpm builds into git status)
  - LLM.md: directory layout reflects reality (main/main.go, not cmd/lpm/),
    document on-disk wrapper format and the chains/ vs subnets/ rename

On-disk Manifest Format

Plugin definitions are YAML files under a repository checkout:

vms/<name>.yaml — wrapped under top-level vm: key
chains/<name>.yaml — wrapped under top-level subnet: key (legacy wrapper key kept for backwards-compat with shipped manifests; the on-disk directory moved from subnets/ to chains/ in plugins-core v0.1.3)

state/repository.go enforces the wrapper. Unwrapped manifests are rejected (was: silently zero-valued T returned, leading to install-vm crashes — see CI-PREMORTEM.md §12a in luxcpp/cevm).
