Freeze body-absence access flags with stable parsed method identity, before
code generation can rewrite method metadata. Skip source slicing for these
methods and return unavailable empty source with explicit native/abstract
markers, rather than attributing neighbouring members to the selected method.
Adapt the access-flag guard and tiny Smali fixtures from PR #3527. Extend real
metadata and public CLI/MCP regressions for native, static native, abstract,
concrete overloads and re-reading frozen facts after neighbouring generation.
Rename the expanded method-body verifier and remove its old entry point.
Validation: 72 focused tests in 3 files; real pinned-JAR baseline control
fails and candidate passes without triggering code generation; 6 real CLI
and 6 MCP fixture calls with parity, identity and unchanged APK; docs/static
checks and two source reviews. Six measured real MCP workflows, no speedup
claim. Tiny authored APK only; reported BinaryEye, Linux/Windows and browser
workflows unverified. Heavy profiling/stress remain stopped.
Fixes#3488
