Add trampoline patcher v5 - counted loop timeouts for all 45 polls

Browse Source

Each poll loop branches to an appended trampoline that:
- Initializes w18 = 0x20000 (128K iterations)
- Copies the original loop body (LDR + condition check)
- Decrements w18, retries until timeout
- Falls through on timeout (no hang)

QEMU verified: original stuck at 0x10350, trampoline progresses through all polls.
Blob grows from 76704 to 78068 bytes (+1364 bytes trampoline section).

NOT YET TESTED ON REAL HARDWARE - the NOP approach bricked the GenBook.
This counted approach preserves the poll loops with a safety timeout.
