Merge branch 'master' into fix/human-transcript-projection

Conflicts, all in files this branch and master both touched:

- `chat/helpers.ts` — kept both sides. Master replaced the inline env
  filter in `gitBranch` with `scrubbedParentEnv()`; this branch added the
  surface-marker and compaction-source imports.
- `docs/module-graph.md` — regenerated. Both sides added a `tui` edge
  (master `subprocess`, this branch `compact`); the generated row now
  carries both.
- Three `.i18n.yaml` pairing records — re-recorded from the merged files.
  Blob hashes cannot be hand-merged, and both sides' prose survives on
  each side of every pair.

`docs/cordis-catalog/services.md` also regenerated for shifted source
lines and master's new `sessionTitle.rename` entry.
