fix(auto-inject): use nm for symbol lookup and fix serial thread safety
Bug 1: _resolve_symbol_addr() used GDB (~0.6s/symbol), replaced with
nm-based fast path via elf_utils.get_symbols() with mtime cache.
9 symbols: 5.4s -> 0.3s (first) / ~0s (cached).
Bug 2: _trigger_auto_inject() spawned a thread that directly called
serial I/O, violating ThreadCheckedSerial ownership. All serial ops
now routed through run_in_device_worker() to fpb-worker thread.
- Add _get_elf_symbols() with lazy mtime-based cache
- Route do_inject/do_unpatch through DeviceWorker
- Add 7 new tests (nm resolve, cache, GDB fallback, worker timeout)
- Update existing auto-inject tests for DeviceWorker mock
- Add postmortem doc1 parent f5f912e commit eadcc47
