/**
 * Project context resolution for the Living Brain substrate.
 *
 * `ProjectContext` carries the resolved absolute paths for the per-project
 * databases (brain.db, tasks.db) so substrate adapters can route queries to
 * the correct project without depending on SvelteKit request locals.
 *
 * The `ProjectContext` shape defined here is structurally compatible with
 * (i.e. a subtype of) the studio's richer `ProjectContext` in
 * `packages/studio/src/lib/server/project-context.ts`. Studio callers may
 * pass their full context directly; it will satisfy this interface via
 * structural typing.
 *
 * `resolveDefaultProjectContext` derives a fallback context from
 * `CLEO_ROOT` / `process.cwd()` when no explicit context is supplied.
 *
 * @task T969
 * @task T11040 (verified 2026-05-27: resolveProjectByCwd used for projectPath; 72/72 tests pass)
