feat(workspace): a yodel project as a chant workspace member, with dbt (#2)

[lex00]

Closes #2

Draft: this waits on chant 0.124.23. That release carries INTENTIUS/chant#3931 (sql tables and columns as workspace outputs), #3932 (the dbt member kind) and #3941 (a member's Ops no longer hide its outputs). Until it's on npm, test/workspace.test.ts fails against the published 0.124.21. Before merging, this PR moves @intentius/chant and @intentius/chant-lexicon-sql to 0.124.23 in package.json.

What changed

• A yodel project works as a kind: "chant" member of a chant workspace, with no other changes. Its tables, views and columns are outputs named as src/ declares them. A dbt member's sources.yml links to them. chant workspace check fails with WSP093, at the dbt file and line, when src/ drops a column a consumer reads. With a -- previously: hint it says what the column was renamed to.
• Every Op yodel writes or prints now has an export name of its own: the templates' and examples' ops/ (migrateDev, watchDev), the ApplyOp and migrate Op examples, and the yodel new --backfill template (backfillFillCountry). A backfill module can export its single Op under any name, and op and the default export still work. Testing against chant main first found that duplicate op exports stopped chant's fold, which left every link unresolved. chant fixed that in #3941, so older projects work as they are. The renames stop new projects from ever exporting the same name twice.
• New docs/workspace.md: the workspace declaration, output names, dbt sources, drops and renames, and the Op export names.

Verified

• npm ci && npm run build && npm run check against chant main packed at 3064f1896 (0.124.22 on main): 834 tests pass, with typecheck and eslint clean.
• test/workspace.test.ts copies each template in as a member, next to an app link and a dbt project, and checks four things:
  • The check passes with no WSP094.
  • A dropped column fails for both consumers.
  • A rename hint is reported.
  • A project made before this change, with every Op and backfill exported as op, still passes and still fails on a drop.
• Checked by hand: a scratch workspace on chant 5c6e6fd37, before #3941, reported every link as WSP094 until the Op exports were renamed. On 3064f1896 the old-style project resolves as it is.
