console_ensure_line_start() (hal/console.c) used to emit its newline
immediately via a path that deliberately skipped the tx-byte counter, so
that sk_repl_idle()'s unconditional per-beat call to it (repl.c, ~1s idle
heartbeat) could force a real newline the REPL's own prompt-reanchor logic
never noticed -- the prompt was never reprinted, and the next real
keystroke echoed onto the now-blank line, indistinguishable from Enter
having already been pressed at a bare prompt. Root-caused in the previous
commit (704573b); this commit applies the fix per explicit go-ahead.
Fix: defer the newline instead of emitting it eagerly.
console_ensure_line_start() now only sets a flag (g_pending_line_close);
the newline is realized -- for real, and counted by g_console_tx_count
like any other output -- on the next actual console_putc() call, or
silently discarded via the new console_cancel_deferred_line_start() if the
caller decides nothing was actually printed. sk_repl_idle() captures
tx_before_idle right after its console_ensure_line_start() call and cancels
the deferred newline at both of its exit points when console_tx_count()
hasn't moved. A beat with nothing to report now leaves the console
untouched; a beat that does print still closes the dangling prompt line
first, properly counted this time. The pre-existing n > 0 mid-edit gate in
sk_console_readline() is untouched -- independent purpose, not the bug.
Verified via the mandatory foreground 3-arch QEMU acceptance boot
(clean qemu, amd64 -> aarch64 -> riscv64, one at a time): all three reached
(zuse) ok>, all echoed the first real input on the same log line as the
prompt rather than a fresh line, all shut down cleanly via BYE. amd64's log
additionally shows live human backspace-correction still glued to the same
prompt line. Logs: logs/20260905-015854 (amd64), logs/20260905-020248
(aarch64), logs/20260905-020552 (riscv64); logs/20260905-015813 is a
foreground-rule-violation retry killed and redone correctly, kept per this
project's "never delete logs/" convention.

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
