Multi-platforms Build with Remote Build Execution

Builds move from local Mac to remote Linux using RBE and firecracker microVMs, running a real repo’s integration tests faster because 1500 cores vs 10 yields multiminute builds and DB-backed tests. Practical work: a Bazel flag combo that builds Linux artifacts from macOS, experimental experimental_platform_in_output_dir to share out dirs, and UI/telemetry for cache and sandbox diagnostics. Footguns: complex C/C++/Java toolchain setup, repository_context‑registered toolchains, and legacy host_cpu/cpu flags that must be set for some rules.
