The "v4" suffix was a holdover from iterative project restarts.
There is now one psxrecomp; all identifiers, include guards, cmake
variables, function names, log strings, schema tags, and tool paths
drop the v4 suffix.
Changes:
- PSXRECOMP_V4_ROOT → PSXRECOMP_ROOT (cmake)
- PSXRECOMP_V4_RUNTIME_SOURCES/_INCLUDE_DIRS/_BIOS_GENERATED → no V4
- psxrecomp_v4_add_runtime_target → psxrecomp_add_runtime_target
- PSXRECOMP_V4_*_H include guards → PSXRECOMP_*_H
- "psxrecomp-v4" log/window strings → "psxrecomp"
- Schema version strings in recompiler JSON output
- Tool script hardcoded absolute paths updated

Two passive, always-on rings for auditing memory-card reads end-to-end
without arming/timing probes:
card_read_summary (non-evicting, first 32 successful reads):
Captured at the MC_READ_END transition in sio_process_byte. Records
slot/cmd/sector/checksum/data_idx/first 16 bytes/cycle/caller func.
TCP cmds: card_read_summary, card_read_summary_reset.
card_data_writes (4096 entries, rolling tail):
Arm side: sio_read(SIO_RX_DATA) sets a pending flag while the card
protocol is in MC_READ_DATA..MC_READ_END.
Check side: psx_write_byte/half/word capture the next RAM write
whose new_val matches the armed RX byte, then disarm.
Records dest addr / value / store_pc / func / mc_idx / slot / cycle.
TCP cmds: card_data_writes, card_data_writes_reset.
Helpers:
tools/probe_card_reads.py
tools/probe_card_writes.py
