Makes the "initial" 8-13.x support from v1.2.5 actually functional. HW-validated on FW 8.xx, 9.xx, 10.xx and 12.xx (all watchpoint types, breakpoints, title id, content id, version etc.). FW-agnostic by design; 11/13.x are lower-risk but not tested. Memory write (poke) on FW >= 8.40: - mdbg write op (0x13) is kernel-gated with EPERM on FW >= 8.40, so pokes failed. Route writes through a DMAP page-table walk (kernel_copyin on the physical alias) on FW >= 8.40; mdbg stays the path on < 8.40 and as a fallback. - PROC_ALLOC pre-faults its pages so writes land on freshly-allocated demand-zero memory. Breakpoints / watchpoints on FW 9.x-13.x: - Extend the kernel-dbreg allowlist to 9.00-13.20; HW BP/WP were silently no-oping on 9.x+. - SW (INT3) breakpoints write the 0xCC via the DMAP path (mdbg rejected it on FW >= 8.40). - Clear DR6 after each debug exception: FW 11/12 stops re-delivering a HW BP/WP trap after a few hits when the sticky DR6 status is left set; plus re-arm the debug regs for data watchpoints. Game ID / Content ID / Version - firmware-agnostic: - Resolve title id and content id by pattern-scanning the proc struct instead of per-FW offsets (which shifted at 8.x and 12.x). - Foreground-app command resolves the title id robustly so the param.sfo game version reads correctly on 12.x. Console crash on client disconnect (SIGPIPE): - Closing the client mid-operation raised SIGPIPE in the server thread and killed the host SceShellCore. Suppress it: MSG_NOSIGNAL on sends + SO_NOSIGPIPE on the sockets. Load notification now shows the running firmware version, and the credits line was updated. Documentation: - Rewrote PROTOCOL.md against the v1.2.6 sources (commands, packet structs, status/bit-swap semantics, scan/xref wire formats, enums). - Corrected and expanded README: per-release firmware support table with verification status, and accuracy fixes throughout. Bump version 1.2.5 to 1.2.6.
