docs(tasks): agenda lists what others owe you; tg 0.72.0

[leemour]

Task

Document the new "assigned" section of tasks agenda on the Tasks page (en/ru/es), and move the docs tg pin to
v0.72.0, the first tg release that carries it (cli-core#1484,
merge 4fe8c553, in Core 0.331.0).

Why

Owner decision 2026-10-17: the agenda shows what others owe the owner. The page told readers to run
tasks list "assignee:any state:open" for that. tg 0.72.0 (Core 0.331.0, Base 0.43.5) is on npm, so the page is no
longer ahead of the installed tg.

What

• content/docs/tasks.md, tasks.ru.md, tasks.es.md: the agenda description, the "Miss nothing" bullet and the
  assignee paragraph say the agenda lists open tasks with an assignee under "assigned", oldest first.
  tasks list "assignee:any state:open" stays as a second way.
• tools.json: tg docsRef v0.71.0 → v0.72.0.
• translations/tg/*.{ru,es}.md: the 0.72.0 changelog entry; the agenda description in commands; search_stemmers.*
  in archive and configuration-reference; cli-contract link to v0.72.0. Fingerprints accepted in
  translations/sources.json after docs:translation check.
• scripts/docs-corrections.json: removed the tg configuration-reference and archive searchStemmers.*
  corrections. tg-cli#602 fixed the native pages, and after
  pnpm sync the synced EN/RU/ES pages contain no searchStemmers; pnpm docs:check passes without them.
• docs/release-notes-review.json advanced to v0.72.0 (roadmap fingerprint unchanged); review record
  docs/reviews/2026-10-18-tg-072-release.md.

Testing

pnpm lint, pnpm search:check, pnpm sync, pnpm docs:release-notes, pnpm test (309 passed),
pnpm docs:contracts, pnpm docs:check, pnpm typecheck, all green locally. Full validation on this PR.

Remaining (native, not changed here)

• cli-core's generated config unset setting list still includes default_profile.
