* fix(renderer): raise renderer V8 heap toward the 4GB pointer-compression cage
Renderer OOM ('renderer crashed'/'oom', exit 5 / 0xE0000008 / SIGTRAP) is the
dominant crash in the crash channel: the renderer JS heap reaches Chromium's
default V8 old-space ceiling (~RAM/4) and V8 aborts. Two adversarial leak hunts
(13 agents across every renderer subsystem) found no unbounded GB-scale leak, so
this is a capacity ceiling, not a leak.
Chromium sizes the renderer heap at ~RAM/4, leaving 8-15GB machines well under
V8's ~4GB pointer-compression cage (an 8GB machine caps near 2.2GB). Reclaim that
unused headroom via --max-old-space-size in a focused startup module, gated on
physical RAM (>=8GB, ~40% of RAM, floor 3072MB, capped at the real 4096MB cage).
16GB+ machines are already at the cage so this is a no-op for them; low-RAM
machines keep the default to avoid trading a clean OOM for OS memory-pressure
kills.
Overridable with ORCA_RENDERER_HEAP_MB (number to force, default/off/0 to opt
out). Verified on Electron 42.3.3: the main-process js-flags switch propagates to
the renderer V8 and is honored up to the 4096MB cage (5000/12288 -> 4096).

* fix(renderer): address CodeRabbit — floor-to-0 override + Linux 8GB gate
- parseRendererHeapOverrideMb: a fractional override in (0,1) floored to 0 and
emitted an invalid --max-old-space-size=0; treat floored-to-0 as an opt-out.
- Lower the RAM gate from 8 to 7.5 GiB: os.totalmem() on Linux reports MemTotal
(excludes kernel/firmware-reserved RAM), so a real 8 GB box reports ~7.7 GiB
and was wrongly excluded from the headroom — the exact crashing population.
7.5 still cleanly excludes 6 GB machines (report ~5.7 GiB).
