The upstream precedence fix (5845a5a) made agent_groups.agent_provider and
sessions.agent_provider authoritative for host-side provider contribution
(per-session mount, env passthrough), but those DB values don't propagate
into the group's container.json — and the in-container runner reads
`provider` from container.json, not from the DB. That caused a confusing
failure mode: flipping the DB column to 'codex', rebuilding, and
restarting still spawned a Claude runner because container.json had no
provider field. The old skill wording ("container receives AGENT_PROVIDER
from the resolved value") overstated the integration.
Update add-codex and add-opencode "Per group / per session" sections to
say: set `"provider": "<name>"` in the group's container.json — that's
the source the runner reads. Keep the DB columns documented for the
host-side contribution they actually drive, and spell out the
session → group → container.json → 'claude' fallback so the precedence
is still discoverable.

The prior instruction told users to append "@openai/codex@${CODEX_VERSION}" to
a single combined `pnpm install -g` block. That block no longer exists on
main — the Dockerfile splits each global CLI (vercel, agent-browser,
claude-code) into its own RUN layer for cache granularity. Update the skill
to add a standalone RUN block for Codex that matches the existing pattern.

Mirrors the /add-opencode and /add-ollama-provider pattern. Copies the
add-codex SKILL.md from the providers branch onto trunk so the skill is
discoverable without a manual branch copy.
