Research update for HackTricks content

🤖 Agent Actions

Updated pointer-redirecting.md with a narrower, more practical expansion of pointer-redirection attacks.

The main additions are: real-world audit guidance for adjacent stack pointers, partial-overwrite notes for repointing pointers without full control, a new section on converting corrupted local pointers into second-stage read/write primitives, and a concise modern AArch64 PAC/BTI note explaining why function-pointer redirection can matter more than return-address overwrites on hardened targets. I kept the page focused on stack-local pointer abuse and avoided duplicating broader ret2win/ROP material already covered elsewhere.
