xhci_bringup() (HC reset, DCBAA, Command/Event rings, RUN/STOP) was
uncommitted and referenced an XHCI_WAIT_FOR macro that was never defined,
breaking the build. Wired all four wait sites to the existing
xhci_wait_bit() helper instead, matching each register/bit/polarity
needed (halt-before-reset waits for HCH set; HCRST, CNR, and post-RUN
HCH waits all wait for their bit to clear).
Also flipped g_doe_log_enabled's default from 1 to 0 -- the per-tick
[HADES][DOE] CSV export was flooding every boot log and slowing
interactive verification for no reason during ordinary acceptance runs;
HB-ON still re-enables it at the REPL for anyone running an actual DoE
campaign.
Three-arch acceptance: amd64/aarch64/riscv64 all boot clean to ok>,
zero DoE rows in any log. aarch64 and riscv64 both exited cleanly via
BYE with no exception, confirming the earlier SMC->HVC PSCI fix still
holds. Logs and DoE CSV artifacts from this run included.

Cursor (Captain Bob: "the only thing we need is a cursor"):
vt100_draw_cursor() draws a solid block at the terminal's current
position, called from repl.c after the prompt prints and after every
keystroke/backspace. vt100_erase_cursor() cleans up the one gap a static
cursor has -- Enter/newline moves away from the cursor cell without a
character draw ever overwriting it, which left a stray block behind
until this fix.
HB-ON/HB-OFF (Captain Bob: run a program with or without instrumentation
without rebuilding):
Converted per-tick DoE logging from a build-time flag (HEARTBEAT_DOE_LOG)
to a runtime one. doe_log_tick_row() now self-gates on g_doe_log_enabled
(default 1, matching the old default) instead of being compiled out
entirely; the call site in vm_runtime.c is unconditional. Two new FORTH
words, HB-ON and HB-OFF, flip the flag live. Removed the now-dead
HEARTBEAT_DOE_LOG plumbing: the Kconfig symbol, and the -D forwarding in
both LOADER_CFLAGS and KERNEL_CFLAGS.
Verified: three-arch clean QEMU boot + logs; dictionary word count 466
(463 baseline + ALT+TAB + HB-ON + HB-OFF, exactly the three words added
across this session); amd64 screendump confirms the cursor renders
correctly after real interactive typing.
