feat(codex): let Codex sessions drive other sessions through the codeman skill

Measured on 1.47.0 with the same "spawn a shell worker, echo, read, delete"
task: DeepSeek Harness and OpenCode already pass end to end; Codex 0.162
failed three ways, fixed here.

- Start Codex 0.162+ with --no-daemon (new noDaemonFlag gate, fail-closed).
  The shared app-server daemon stopped every launch on an "incompatible
  feature settings" dialog when another version's daemon was running, and
  ran commands with another session's CODEMAN_* environment.
- Evaluate registry version gates against the gated CLI's own version
  (resolveSessionCliVersion) instead of claude's for every entry.
- Add the opt-in synced setting App Settings > Codex > Allow network access
  (codexNetworkAccess, default off): --config
  sandbox_workspace_write.network_access=true, filled as a launch default
  and clamped off for non-granted owners like the bypass switch.
- Skill: carry on with the curl path when `codeman` is not on PATH, re-run a
  sandbox-blocked call once through the CLI's approval path, name the new
  setting. Wiki and registry docs updated.

 Two things to know:

+- Codex's default sandbox blocks network access, even to this machine, so turn on

+  drive others. It applies to Codex sessions started after you switch it on, and it keeps
+  Codex's sandbox and approval prompts. It opens the network only where Codex runs the
+  folder in its workspace-write sandbox, which is what Codex does for a project you
+  trusted. In a folder Codex runs read-only (a new case that is not a git repository, for
+  one), Codex asks you to approve each call to Codeman instead; `/permissions` in Codex
+  switches that session to workspace-write. **Bypass approvals and sandbox** works
+  everywhere, but removes the sandbox and the approval prompts.

-The skill checks for both and says so instead of acting.
+OpenCode and DeepSeek Harness need nothing extra: in their default setup neither keeps its
+shell commands off the network, so the skill works there as soon as it is injected.
