The README had grown into one long page where the basic flashing workflow was buried between VIP, multi-programmer, ramdump, kickstart, WSL2 and raw sector guides. Keep only the generic material in the README and move each specialised workflow into its own file under docs/, linked from a new "Documentation" index. The moved text is unchanged apart from heading levels and two cross-references. Signed-off-by: Igor Opaniuk <igor.opaniuk@oss.qualcomm.com>

Collect crash dump
When a Qualcomm target crashes or is forced into crash dump mode, the
bootloader re-enumerates the device over USB with Product ID 900e and
offers memory segments for collection via the Sahara protocol.
A kernel crash can be triggered on the target with:
echo c > /proc/sysrq-trigger
Use qdl ramdump on the host to collect the dump:
qdl ramdump -o ./ramdump
Each offered memory segment is written to a separate file under
./ramdump. To collect only specific segments, pass a comma-separated
filter:
qdl ramdump -o ./ramdump OCIMEM,CODERAM
