Add 7 heavy exploitation modules: USB shell, crypto attacks, memory editing, privesc, DMA

Interactive exploitation toolkit for authorized home-lab testing:

- USB Shell: interactive CLI over USB serial, direct memory/GPIO access (peek/poke)
- Crypto Attack: dictionary attacks, weak-key detection, MD5/SHA1 cracking
- MemEdit: direct SRAM/DRAM read/write, MPU bypass attempts, page table dumps
- Boot Exploit: bootloader detection + default-password attempts, firmware rollback
- FW Patch: binary find/replace in firmware, auth check neutering, config patching
- PrivEsc: stack smash, use-after-free, integer overflow, race condition exploits
- DMA Attack: simulated DMA transfers to bypass MMU/MPU, kernel memory access

Now 25 total modules covering discovery, analysis, injection, and exploitation.
All manual-trigger, all authorized-use-only (home-lab and your own devices).
README updated with exploitation tier table.

+| Module | What it does |
+|--------|--------------|
+| **USB Shell** | Interactive CLI over USB serial — read/write memory addresses, GPIO control, direct hardware access. |
+| **Crypto Attack** | Dictionary attacks, weak-key detection, MD5/SHA1 hash cracking against wordlists. |
+| **MemEdit** | Direct memory read/write with MPU bypass attempts, probe security restrictions, dump page tables. |
+| **Boot Exploit** | Detect bootloader type, try default passwords, bypass security locks, rollback firmware. |
+| **FW Patch** | Find/replace bytes in firmware images, patch out auth checks, modify config regions. |
+| **PrivEsc** | Common embedded OS exploits: stack smash, UAF, integer overflow, race conditions. |
+| **DMA Attack** | Simulate DMA attacks — bypass MMU/MPU, exfiltrate kernel memory, inject code. |
