- Parses the DTC vector table described by the manual.
- Scans unreached ROM ranges for ASCII strings and pointer-table candidates.
- Emits function summaries and a direct-call graph in JSON, with optional Graphviz DOT output.
- Adds Appendix A cycle estimates to JSON and can append them to ASM comments.
- Handles the E-clock transfer instructions `MOVFPE` and `MOVTPE`.
