feat: add tender review team preview (#160)

## What this changes

Adds the tender-review team and its onboarding entry to the official
Market catalog as an immutable source pointer, plus bilingual catalog
sidecars.

- `teams/biao-shu-lian-he-shen-cha/entry.json` points to the published
team commit `7ee5650b066cdee385288a722b8cbd8e1947d0fe`.
- `agents/tender-review-assistant/entry.json` points to assistant commit
`4b6855d2edb535f81c29847e06145c0da87942d0`.
- Both entries include bilingual descriptions, privacy boundaries and
`requiredClientVersion: 10.0.155`.
- The listing is deliberately `pointer` / preview. It does not claim the
v10.0.155 release is fully green or production-certified; newcomer
qualification remains pending.

## Validation

- `python3 scripts/catalog/validate_catalog_metadata.py --json` — 0
errors (existing catalog warnings unchanged).
- Market entry and both `catalog-metadata.v1.json` sidecars validate
against the current client/catalog schemas.
- Published source repositories and full commit pins were checked before
creating this branch.
