Two related bin-linking behaviors deferred from #333. Behavior 1 — hoisted-bin precedence: - Add `BinOrigin { Direct, Hoisted }` discriminator to `PackageBinSource`. - New top tier in `pick_winner`: Direct wins outright over Hoisted regardless of ownership / lexical order. Mirrors upstream's `preferDirectCmds` partition at https://github.com/pnpm/pnpm/blob/4750fd370c/bins/linker/src/index.ts#L92. - New `link_top_level_bins(modules_dir, direct, hoisted)` helper in `pacquet-package-manager` mixes both candidate lists into one `link_bins_of_packages` call so the new tier resolves conflicts in a single pass — previously the two passes (SymlinkDirectDependencies for direct + hoist pass for publicly-hoisted) wrote shims independently and a hoisted bin could shadow a direct one when its package name was lexically smaller. Behavior 2 — lifecycle-script-created bins: - Add a post-`BuildModules` per-importer top-level bin link pass. Re-reading each direct dep's `package.json` after lifecycle scripts run picks up bins generated by `postinstall` (the `@pnpm.e2e/generated-bins` upstream fixture). Idempotent for unchanged shims via `is_shim_pointing_at`. - Mirrors upstream's `linkBinsOfImporter` pass that runs after `buildModules` at https://github.com/pnpm/pnpm/blob/4750fd370c/installing/deps-installer/src/install/index.ts#L1539. Supporting changes: - `PackageBinSource::new(location, manifest)` constructor + `with_origin` builder so existing call sites don't have to spell out the new field. - Public `direct_dep_names_for_importer` helper extracted from `SymlinkDirectDependencies` so the post-build pass uses the same filter (skipped / first-wins / link_only) as the symlink phase. - `InstallFrozenLockfileError::TopLevelBinLink` for the new failure surface. Tests: - `direct_origin_wins_over_hoisted_regardless_of_lexical` — pins the new tier overrides lexical ordering. - `hoisted_origin_loses_to_existing_direct` — pins both arms of the new tier (Direct incumbent vs Hoisted candidate).
