fix: prevent codex exec stdin deadlock with </dev/null redirect

codex CLI 0.120.0+ blocks indefinitely when stdin is a non-TTY pipe
(Claude Code Bash tool, background bash, CI). The CLI sees a non-TTY
stdin and waits for EOF to append it as a <stdin> block, even when the
prompt is passed as a positional argument.

Fix: add < /dev/null to every codex exec and codex review invocation
in the source-of-truth files (scripts/resolvers/*.ts and *.md.tmpl).
Generated SKILL.md files will be produced by bun run gen:skill-docs
in a subsequent commit (Tension D: template+resolver only, generator
is authoritative, not cherry-picked artifacts).

Affected source files (16 total invocations):
- scripts/resolvers/review.ts (4)
- scripts/resolvers/design.ts (3)
- codex/SKILL.md.tmpl (5)
- autoplan/SKILL.md.tmpl (4)

Fixes #971
