v1.91.159.0 security: gstack's Bun entry points ignore the audited repo's .env and bunfig.toml (S1) (#3312)

* security: isolate every gstack Bun entry point from the audited checkout's .env and bunfig.toml

Bun auto-loads .env, .env.local and .env.<NODE_ENV> from its cwd and runs a
cwd bunfig.toml preload before the program starts. gstack runs inside the repo
it audits, so a committed .env could steer state roots, the claude binary or
spend caps, and a bunfig preload ran arbitrary code in every bin and hook.

Every bun shebang, shell and skill caller, TypeScript spawn and compiled build
now disables both (--no-env-file --config=/dev/null, bunIsolationArgs(),
--no-compile-autoload-dotenv/bunfig), with a ratchet and hostile-fixture
regressions.

* test: name the directly executed scripts in the isolation ratchet

* test: follow the isolation flags in touchfiles, copy lists, recipe assertions and the harness pin

* fix: keep browse/src/bun-child-config.ts unchanged so the native cookie qualification still binds

* fix(windows): the empty bunfig outlives its process so the timeline hook's detached repair child can read it
