* fix(#2834): write defaults.json before agent TOML generation on clean Codex install
Extracted writeNonClaudeDefaults(runtime) and called it BEFORE installCodexConfig
so the runtime-aware model resolver has resolve_model_ids=omit + runtime=codex in
~/.gsd/defaults.json before agent TOMLs are generated. Pre-fix, a clean first Codex
install generated TOMLs with no model fields (the resolver didn't know the runtime);
a second run fixed it. The original inline defaults-write block (which ran AFTER agent
generation) is replaced by the earlier function call (idempotent).
* chore(#2834): changeset fragment
* fix+test(#2834): acknowledge codex TOML drift (emitted-attribution) + fix test comment window
The emitted-attribution gate flags 19 codex agent TOMLs that now carry model-routing
fields (the fix's correct effect) but can't link them to a .md or src/ change (the fix
is in bin/install.js ordering). Acknowledge the drift in emitted-drift-ack.json. Fix the
test's comment-detection window (300 chars to capture the #2834 rationale).
* fix(#2834): ack remaining 15 codex TOML drift paths
* chore(#2834): backfill changeset PR number (2900)
* chore(#2834): ack code-review.md growth from concurrent merge (rebase pickup)
* fix(#2834): remove stale code-review.md ack (emitted-attribution failure)
CI failed: 'differential attribution over the real tree' — the code-review.md
ack added in 6e0b4b3b8 ('ack code-review.md growth from concurrent merge') is
STALE: this PR's diff does not touch code-review.md (only bin/install.js + tests
+ changeset), so the ack explains growth that isn't here. The base already
absorbed the concurrent code-review.md growth; the ack is inert here and the
gate flags it as stale. Remove it.
