yetone 06420a7121 tests: a fake program is a file macOS has already let run (testenv.Program), so a fake's first start no longer eats a test's wait under load
macOS checks a newly written executable before its first exec: 0.27s
alone, 2-5s while other new programs start (a go test ./... starting its
test binaries). The same file again takes 0.009s, and the pass is kept
across a rename and an in-place rewrite. 108852b4 worked round this for one
test with /bin/sh -c; the class was every test that writes a `#!/bin/sh`
fake and times its answer.

testenv.Program(t, path, script) replaces os.WriteFile(path, script, 0o755)
for fakes. On macOS it renames a file that has run once from a pool to path
and writes the script into it in place; at the test's cleanup the file goes
back to the pool (only a path the test created; a stand-in it wrote over
stays). Fakes still end with their tests: nothing about how they are
started or waited on changed. Run (and gateway's TestMain) remove the pool
at the end. TestMain's PATH stand-ins are run once in the background
(testenv.StandIns). Other systems write the file as before.

Converted every `#!/bin/sh` fake written by tests under internal/ (agent,
gateway, gui, library, plugin, proc, provider, update). Windows, binary
and node/bun fakes are unchanged.

Under the same load (3 loops each starting 8 freshly written scripts at a
time), 4 rounds each, before (108852b4 / origin/main) vs after:
- provider TestSavedButSignedOutClaudeServed: 4/4 fail (8.01s) -> 4/4 pass
- provider TestClaudeSignInOverStaleCredentials: 4/4 fail (5.00s) -> 4/4 pass
- provider TestDevinSignedInOnlyInMagpie: 3/4 fail ("CLI's own []") -> 4/4 pass
- gateway TestClaudeRunEndsWhenTheClientLeaves: 4/4 fail -> 4/4 pass
  (and 3/3 fail -> 3/3 pass at a third of that load)
- gateway TestClientGoneRecordedAsCanceled: 4/4 fail -> 4/4 pass
- gui TestProvidersAnswerWhileListsComeIn ("cursor found false" at 3.03s):
  4/4 fail -> 4/4 pass. The same class, not bfe8bcaf's test order.
- proc TestUserPath (login shell's PATH never came, 7.01s): 4/4 fail ->
  4/4 pass
Unloaded, every touched package passes; no pool directory or process is
left after a run.
