In `web/src/projection.ts` ONLY, update stale references to the Rust source file. `src/projection.rs` moved to `quacker-core/src/projection.rs` in the quacker-core extraction (PR #312); the top-level `src/projection.rs` no longer exists. This file references the old path in ~17 comment spots — both TypeScript `/* … */` / `*` doc comments and `-- …` SQL comments inside the DDL template strings, including symbol references like `src/projection.rs::tag_attributions`.

Replace every occurrence of the path `src/projection.rs` with `quacker-core/src/projection.rs` in this file. Keep any `::symbol` suffix and all surrounding comment text exactly as-is.

Constraints:
- Edit ONLY `web/src/projection.ts`. Touch no other file.
- Change ONLY the path string `src/projection.rs` → `quacker-core/src/projection.rs`. These are all comment / doc references — do NOT change any TypeScript logic, SQL table/column names, string values, or anything other than the path inside those comments.

This is a mechanical path update for a moved file.
