xenia-app: observability subsystem, --parallel runtime, stress harness

Browse Source

observability.rs installs the tracing subscriber stack (env-filter +
JSON file appender + chrome trace + error layer) and the metrics
recorder shared by the workspace. main.rs grows the new CLI surface:
--parallel, --reservations-table, --trace-handles, --analyze=
{rust,sql,both}, xenia dis --json, --ui, plus the wiring that runs
the CPU through the new scheduler, drives the GPU's threaded backend,
and surfaces the framebuffer + HUD via xenia-ui.

Add tests/parallel_stress.rs (#[ignore]-gated long form, short form
runs 20×@5M) and tests/golden/sylpheed_n2m.json — the digest the
lockstep/parallel combos compare against.
