test(cli): deflake cli-setup-opencode.test.ts — silence console (#5959-class landmine) (#6033)

The command under test prints CLI progress with multi-byte glyphs
(printSuccess "✔" in the happy paths, printError "✖" in the dist-missing
path that test 4 exercises) via console.log. Under the node:test runner
those child-stdout writes interleave with the V8-serialized report frames
and can corrupt the stream — the exact #5959 mechanism proven for
setup-claude.test.ts; this file's ✖ line was already visible entangled in
red CI runs. No test here asserts on stdout, so silence console.log/info/
warn for the file (same pattern as #6019/#6021, restored in after()).

Validation: pre-fix the ✖/✔ lines reach stdout every run (grep-able);
post-fix stdout is clean, 4/4 tests green, 0/20 failures across 20 runs.

 ### 🔧 Bug Fixes
 
 - **tests(cli):** stabilize `setup-claude.test.ts` (#5959) — the dry-run path printed a multi-byte "──" heading to the test child's stdout, corrupting the node:test runner's V8-serialized event stream in ~50% of runs ("Unable to deserialize cloned data due to invalid or unsupported version") and randomly failing the PR→release queue. `syncClaudeProfilesFromModels` now accepts an injectable `log` sink (CLI default unchanged: `console.log`); the test injects a collector and gains assertions on the dry-run report. Validated 0/30 failures post-fix vs 5/10 on the pristine base.
+- **tests(cli):** deflake `cli-setup-opencode.test.ts` preemptively — same #5959 class: the command under test prints multi-byte "✔"/"✖" CLI glyphs to the test child's stdout, which can corrupt the node:test V8 report stream. Console silenced for the file (pattern of #6019/#6021); no test asserts on stdout. 0/20 failures, stdout clean.
 - **tests(ci):** collect the orphaned `tests/unit/executors/` directory (created by #5800 outside every runner glob — its 2 test files never ran anywhere). Added `executors` to the unit-runner brace globs (package.json, ci.yml shards, quality.yml TIA, test-impact map, test-discovery gate); both files pass (10/10).
