[codex] Align help-flow workflow references

[breezeFur]

Summary

• replace the deprecated self-help-flow entry in the canonical workflow list with help-flow
• align the active help-flow root tag and handoff text with its workflow name
• regenerate the seven checked-in IDE plugin copies from the R3 source

Root cause

help-flow was split from the deprecated compatibility workflow, but its body retained the old self_help_flow wrapper and self-reference. The canonical workflow list also continued to expose only the deprecated name.

Before / after

• Before: the workflow list pointed readers to self-help-flow, while help-flow declared <self_help_flow>.
• After: the list points to help-flow, and all source/generated copies declare <help_flow> and refer to Help-flow in the handoff.

Validation

• npx -y rosettify-plugins@latest --release r3 --deterministic-hooks false
• verified the R3 source plus all seven generated plugin copies contain matching name: help-flow, <help_flow>, and </help_flow> values
• verified the canonical list contains help-flow and no active self-help-flow entry
• git diff --cached --check

Closes #276
