Diego Rodrigues de Sa e Souza be9f43e1ee cherry-pick(pr-9695): fix(docker): make the webpack build-arg escape hatch actually work (#9872)
* build(docker): make the bundler build-arg actually take effect

A bare ENV shadows a same-named ARG for the rest of the stage, so
--build-arg OMNIROUTE_USE_TURBOPACK=0 was silently ignored and the
webpack escape hatch the surrounding comment advertises only ever
worked through -e at runtime, never at build time.

That mattered because Turbopack compiles in native Rust memory living
outside the V8 heap, so OMNIROUTE_BUILD_MEMORY_MB cannot bound it. A
build host with a memory ceiling gets SIGKILLed by the cgroup OOM
killer with no error text at all, which reads like a hung build rather
than an out-of-memory one.

* docs(docker): correct the builder stage facts and document its cost

The stage table described a builder that no longer exists: it named
node:24.15.0-trixie-slim where every stage now derives from
node:26-trixie-slim, and said the stage runs `npm run build -- --webpack`
where it runs plain `npm run build`, which is Turbopack by default.

That second one is worse than stale. A reader who needs the webpack
fallback would conclude the Docker build already uses it and never look
for the switch.

Adds a Build-time resources section covering the two build args, why the
V8 heap arg cannot bound Turbopack, and measured ceilings for both
bundlers. The runtime paragraphs that followed get their own heading so
they no longer read as part of the build-time story.

* docs(docker): correct the runtime heap defaults

Same drift as the builder stage, in the paragraphs just below it. The
image exports OMNIROUTE_MEMORY_MB=1024 and derives NODE_OPTIONS from it,
but the guide reported 512 in three places, including the environment
variable table.

The "if unset, the launcher uses 512" line was misleading in both
readings: the image always sets the variable so that branch cannot fire
under Docker, and outside Docker the launcher calibrates from host RAM
rather than using a flat 512.

* docs(changelog): add fragment for #9695
