First step of the public-viewing feature (design: docs/design/tree-visibility.md).
No non-member behavior change yet — this only widens the vocabulary and UI.
- TreeVisibility gains `site_members` (any authenticated user of the instance),
giving the four-level model: public / site_members / unlisted / private.
- Alembic migration adds the enum value via an autocommit block (ALTER TYPE
ADD VALUE can't run in a transaction on older Postgres); downgrade is a no-op
since PG can't drop an enum value.
- Regenerated openapi.json + frontend TS client.
- Trees-list dropdown now offers Private / Public – Members / Unlisted / Public
with an explanatory tooltip.
