* feat: add `dedupePeers` option to reduce peer dependency duplication
When enabled, this option applies two optimizations to peer dependency resolution:
1. Version-only peer suffixes: Uses name@version instead of full dep paths
(including nested peer suffixes) when building peer identity hashes.
This eliminates deeply nested suffixes like (foo@1.0.0(bar@2.0.0)).
2. Transitive peer pruning: Only directly declared peer dependencies are
included in a package's suffix. Transitive peers from children are not
propagated upward, preventing combinatorial explosion while maintaining
correct node_modules layout.
The option is scoped per-project: each workspace project defines a peer
resolution environment, and all packages within that project's tree share
that environment. Projects with different peer versions correctly produce
different instances.
Closes#11070
* fix: pass dedupePeers to getOutdatedLockfileSetting and use spread for lockfile write
The frozen install path (used by approve-builds) calls getOutdatedLockfileSetting
but was missing the dedupePeers parameter. This caused a false LOCKFILE_CONFIG_MISMATCH
error because the lockfile had the key written (as undefined/null via YAML serialization)
while the check function received undefined for the config value.
Fix: pass dedupePeers to the settings check call, and use spread syntax to only write
the dedupePeers key to lockfile settings when it's truthy (avoiding undefined keys).
* fix: write dedupePeers to lockfile like other settings
Write the value directly instead of spread syntax, and use the same
!= null guard pattern as autoInstallPeers in the settings checker.
* test: add integration test for dedupePeers in peerDependencies.ts
* fix: only write dedupePeers to lockfile when enabled
When dedupePeers is false (default), don't write it to lockfile settings.
This avoids adding a new key to every lockfile.
* test: simplify dedupePeers test assertions
* test: check exact snapshot keys in dedupePeers integration test
* test: add workspace test for dedupePeers with different peer versions
* fix: keep transitive peers in suffix with version-only IDs
Instead of pruning transitive peers entirely (which prevented per-project
differentiation), keep them but use version-only identifiers. This way:
- Packages like abc-grand-parent still get a peer suffix when different
projects provide different peer versions (correct per-project isolation)
- But the suffixes use name@version instead of full dep paths, eliminating
the nested parentheses that cause combinatorial explosion
* refactor: extract peerNodeIdToPeerId helper in resolvePeers
* refactor: simplify peerNodeIdToPeerId return
* fix: pin peer-a dist tag in dedupePeers tests for CI stability
* fix: address review comments
- Register dedupe-peers in config schema, types, and defaults so
.npmrc/pnpm-workspace.yaml settings are parsed correctly
- Use Boolean() comparison in settings checker so enabling dedupePeers
on a pre-existing lockfile triggers re-resolution
- Fix changeset text and test names: transitive peers are still
propagated, just with version-only IDs (no nested dep paths)
* fix: ensure PNPM_HOME/bin is in PATH during pnpm setup
When upgrading from old pnpm (global bin = PNPM_HOME) to new pnpm
(global bin = PNPM_HOME/bin), `pnpm setup` would fail because the
spawned `pnpm add -g` checks that the global bin dir is in PATH.
Prepend PNPM_HOME/bin to PATH in the spawned process env so the
check passes during the transition.

* fix: revert tempy to 3.0.0 to fix bundle hang
tempy 3.2.0 pulls in temp-dir 3.0.0 which uses async fs.realpath()
inside its module init. When bundled by esbuild into the __esm lazy
init pattern, this causes a deadlock during module initialization,
making the pnpm binary hang silently on startup.
Keeping tempy at 3.0.0 which uses temp-dir 2.x (sync fs.realpathSync).

* refactor: move getConfig from cli/utils to pnpm CLI package
getConfig and installConfigDepsAndLoadHooks were the only functions in
cli/utils that pulled in heavy deps (env-installer, store.connection-manager,
hooks.pnpmfile, default-reporter). Moving them to the pnpm CLI package
(their only consumer) dramatically reduces the dependency weight of
cli/utils, breaking the circular tsconfig reference chain that previously
required fs.find-packages to be a separate package.

Add n/prefer-node-protocol rule and autofix all bare builtin imports
to use the node: prefix. Simplify the simple-import-sort builtins
pattern to just ^node: since all imports now use the prefix.
Add eslint-plugin-simple-import-sort to enforce consistent import ordering:
- Node.js builtins first
- External packages second
- Relative imports last
- Named imports sorted alphabetically within each statement
Update all packages from zkochan/packages to their latest major versions
and exclude them from minimumReleaseAge requirement. This includes
updating catalog entries, adapting to breaking API changes (default
exports replaced with named exports, sync functions renamed with Sync
suffix), and updating type declarations.
* fix: detect overrides and other lockfile-affecting setting changes in optimisticRepeatInstall
When optimisticRepeatInstall was enabled, changing overrides,
packageExtensions, ignoredOptionalDependencies, patchedDependencies,
or peersSuffixMaxLength would not trigger a reinstall because these
settings were not tracked in the workspace state file.
* refactor: extract WORKSPACE_STATE_SETTING_KEYS to prevent type/runtime drift
The settings key list in createWorkspaceState's pick() call must stay
in sync with the WorkspaceStateSettings type. Extract a shared const
array so both the type and runtime pick are derived from a single
source, preventing the class of bug fixed in the previous commit.
* chore: create empty new `@pnpm/yaml.document-sync` package

This was causing a test to fail due to the rootProjectManifestDir being
an empty string.
The main branch doesn't have this problem because `write-yaml-file`
internally does a `path.dirname(...)` call that ends up resolving the
empty string to `.`.
