Add various scripts and JSON plans for Ghidra project

- Introduced `seg043_boundary_repair.json` to manage function boundaries in segment 043.
- Created `read_file.py` for reading and printing file content size.
- Added `resolve_bb4f.py` to resolve specific function call targets.
- Implemented `resolve_top_targets.py` to find resolved NE targets for top-called wrapper functions.
- Added `script_contents.txt` to summarize NE relocation far calls.
- Updated `tier4_ghidra.txt`, `tier4_ghidra_check.txt`, `tier4_output.txt`, and `tier4_result.txt` with function call statistics.
- Created `tier5_errors.txt` for error logging and `tier5_output.txt` for additional function call statistics.
- Established `tools` directory with helper scripts for the Ghidra project, including CLI and common functionalities.
- Implemented command-line interface in `cli.py` for various project operations.
- Added `common.py` for shared functions and configurations across tools.
- Introduced `validate_fixups.py` to validate NE relocation fixups against known addresses.
