shanglei 2098c3c412 perf(registry): drop embedded meta_data.json and the larkmeta build tag
The startup baseline now comes solely from the generated static Go registry
(metastatic.Registry), wired into the stub-declared Registry via a package-level
var plus an init() struct-header copy. No build tag, no committed generated
file, and zero startup allocation is preserved.

- gen.go emits a tag-free `var registryData` + `func init()` instead of a
  //go:build larkmeta top-level `var Registry`; stub.go declares Registry
  unconditionally so the package always compiles
- fetch_meta.py regenerates the static registry after fetching, so every build
  and CI step that fetches also produces it (no separate gen step, no CI change)
- remove the //go:embed meta_data.json baseline and the JSON parse fallback;
  meta_data.json is now only the build-time input to the generator
- EmbeddedSpec/EmbeddedServiceNames read the static baseline; drop the schema
  key-order machinery so envelope field order is alphabetical (JSON Schema
  property order is not semantic; parameterOrder for positional args is intact)
- drop -tags larkmeta from Makefile, .goreleaser.yml, and build-pkg-pr-new.sh

Command tree is byte-identical (8092 lines). registry/schema/cmd unit tests,
the zero-alloc bench, and the e2e dry-run suite all pass.

// Tree-dump tool: dumps the full command tree (paths, flags, descriptions,
// annotations) in a canonical, line-stable form so two builds can be diffed
// byte-for-byte (e.g. before/after a registry change). Set LARK_TREE_DUMP=<path>
// to write the dump; otherwise the test is a no-op. Not a committed golden — the
// meta data is fetched/gitignored and drifts.
