Implemented canonical Yoi local Ticket backend provider config.

Final backend config schema:

[backend]
provider = "builtin:yoi_local"
root = "work-items"

provider = "builtin:yoi_local" is the canonical spelling. Existing kind = "local" config is accepted as a short transitional alias so existing local workspaces/tests do not break during the migration, but docs now show the provider spelling.

Default root behavior intentionally remains <workspace>/work-items for missing config and for this transitional provider config. This ticket did not move storage to .yoi/tickets; that is owned by the follow-up migrate-ticket-storage-to-yoi-tickets ticket.

Implementation commit was merged from branch work/builtin-yoi-local-ticket-backend-config.
