Report weak types in object member declarations

[rogerchappel]

Summary

• report interface and direct object type-alias properties, method signatures, and index signatures as deterministic NodeInfo entries
• preserve existing function and inline variable annotation coverage semantics
• make any precedence deterministic inside unions, intersections, and generic arguments
• document the exact object-member finding scope

Commits

• test: cover object member annotations — adds focused interface/type-alias fixtures and variable-semantics regression coverage
• feat: report interface and type alias members — walks member declarations and fixes nested weak-type precedence
• docs: define object member finding scope — aligns README and NodeInfo kind documentation

Verification

• npm ci
• npm run release:check (95 tests; audit, typecheck, lint, coverage, build, CLI smoke, package smoke)
• git diff --check origin/main...HEAD
