refactor: Use package knowledge in the LSP (#13468) ### Description Part 13 of the package/scope knowledge completion stack. Back LSP package identity, root scope, and definition paths with `PackageGraph` while retaining parsed manifest source solely for scripts and ranges. Unnamed/ambiguous manifests remain unqualified best-effort payloads, outputs are deterministic, and graph-backed package views are cached between document edits. ### Testing Instructions - `cargo test -p turborepo-lsp` - `cargo clippy -p turborepo-lsp --no-deps --all-targets -- -D warnings` _{CLOSES TURBO-5777}
