fix(tools): satisfy doc gates for the Python SDK renderer

- Delink dsh-code-runtime-python README references (that package ships in
  a later PR of the split; keep the package name unlinked meanwhile).
- Add the mandatory `## Alternatives considered` and `## Consequences`
  sections to the language-dispatch Agent Note.
- Regenerate config/cordis catalogs and the event graph for the shifted
  index.ts source lines; re-record the README and note i18n pairings.
