test: introduce planner-backed test runner, stabilize local builds (#54650)

* test: stabilize ci and local vitest workers

* test: introduce planner-backed test runner

* test: address planner review follow-ups

* test: derive planner budgets from host capabilities

* test: restore planner filter helper import

* test: align planner explain output with execution

* test: keep low profile as serial alias

* test: restrict explicit planner file targets

* test: clean planner exits and pnpm launch

* test: tighten wrapper flag validation

* ci: gate heavy fanout on check

* test: key shard assignments by unit identity

* ci(bun): shard vitest lanes further

* test: restore ci overlap and stabilize planner tests

* test: relax planner output worker assertions

* test: reset plugin runtime state in optional tools suite

* ci: split macos node and swift jobs

* test: honor no-isolate top-level concurrency budgets

* ci: fix macos swift format lint

* test: cap max-profile top-level concurrency

* ci: shard macos node checks

* ci: use four macos node shards

* test: normalize explain targets before classification
