* fix: overwrite npm .cmd wrappers for @pnpm/exe on Windows
npm creates .cmd wrappers that invoke bin entries through `node`,
but @pnpm/exe bins are native executables, not JavaScript files.
This causes pnpm commands to silently fail on Windows.
* fix: copy pnpm.exe to .bin/ on Windows for standalone mode
The .cmd wrapper approach didn't work because CMD doesn't properly
wait for extensionless PE binaries. Instead, copy the actual .exe
(and .cmd for pnpx) from @pnpm/exe into .bin/ so PATHEXT finds
pnpm.exe directly, bypassing npm's broken node-wrapping shim.
* fix: add @pnpm/exe dir to PATH on Windows instead of .bin shims
On Windows, npm's .bin shims can't properly execute the extensionless
native binaries from @pnpm/exe. Instead of trying to fix the shims,
add the @pnpm/exe directory directly to PATH where pnpm.exe lives.
* test: validate pnpm --version output in CI
All version checks now capture output and assert it matches a semver
pattern. Previously, a silently failing pnpm (exit 0, no output)
would pass the tests.
* debug: log pnpm --version output during setup
* fix: remove duplicate addPath in setOutputs that shadowed pnpm.exe
setOutputs called addPath(node_modules/.bin) AFTER installPnpm had
already added the correct path (@pnpm/exe on Windows). Since
GITHUB_PATH entries are prepended, .bin ended up first in PATH,
causing PowerShell to find npm's broken shims instead of pnpm.exe.
* fix: add PNPM_HOME/bin to PATH on all platforms
* fix: address review feedback — PATH ordering and regex anchoring
- Swap addPath order so pnpmHome (with pnpm.exe) is prepended last
and has highest precedence over pnpmHome/bin.
- Anchor version regex with $ and allow prerelease suffixes.
* feat: read pnpm version from devEngines.packageManager field
When no version is specified in the action config or the packageManager
field of package.json, fall back to devEngines.packageManager.

* feat: skip self-update for devEngines.packageManager and add CI tests
pnpm auto-switches to the right version when devEngines.packageManager
is set, so self-update is unnecessary. This also enables range support
(e.g. ">=9.15.0") which self-update doesn't handle.

When packageManager is set to e.g. "pnpm@9.1.0+sha...", strip the
"pnpm@" prefix and any "+sha..." hash suffix so the action installs
the correct version. Previously returning undefined caused failures
on Windows.
* feat!: replace bundled pnpm binary with npm + lockfile bootstrap
Remove the 9MB bundled pnpm.cjs/worker.js and instead use npm ci with
committed package-lock.json files (~5KB) to install a bootstrap pnpm,
which then installs the target version with integrity verification via
the project's pnpm-lock.yaml.
Also switch from ncc to esbuild and modernize to ESM.

* fix: bundle as CJS to support @actions/* packages
The @actions/* packages use CJS require() for Node.js builtins,
which fails with "Dynamic require of 'os' is not supported" when
bundled as ESM. Switch esbuild output to CJS format.

* fix: remove "type": "module" from package.json
Node.js treats dist/index.js as ESM due to "type": "module",
but the bundle uses CJS require() calls. Remove the field so
Node.js defaults to CJS for .js files.

* fix: remove packageManager field and fix Windows npm spawn
- Remove packageManager from package.json to avoid version conflict
when the action tests against itself (uses: ./)
- Use shell: true on Windows so spawn can find npm.cmd

* fix: always use pnpm (not @pnpm/exe) for bootstrap and update lockfile
The bootstrap only needs regular pnpm to install the target package.
@pnpm/exe requires install scripts which we skip with --ignore-scripts.
Also regenerate pnpm-lock.yaml to match current package.json.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: use --no-lockfile for target install
--lockfile-dir pointing to GITHUB_WORKSPACE causes the bootstrap pnpm
to use the project's pnpm-lock.yaml (which tracks project deps, not
pnpm itself), corrupting the install. Revert to --no-lockfile for now.
Lockfile-based integrity verification can be added when pnpm v11 has
proper support for verifying the pnpm package itself.

* fix: run bootstrap pnpm via node instead of bin shim
Use `node .../pnpm/bin/pnpm.cjs` to run the bootstrap pnpm, matching
the approach used by the old bundled pnpm.cjs. This avoids issues with
the .bin symlink on different platforms.

* refactor: use pnpm self-update instead of installing target separately
- Bootstrap pnpm via npm ci (verified by lockfile)
- Use `pnpm self-update <version>` for explicit version
- Let pnpm handle packageManager field automatically
- Remove standalone/exe-specific install logic (pnpm handles this)
- Update tests to not run pnpm install against the action repo itself

* feat: support standalone mode with @pnpm/exe bootstrap
- When standalone=true, bootstrap with @pnpm/exe via npm ci
- When standalone=false, bootstrap with pnpm via npm ci
- Both use pnpm self-update to reach the target version
- Remove --ignore-scripts from npm ci so @pnpm/exe install scripts run
- Add standalone test back to CI

* debug: add logging to diagnose pnpm not found on PATH
Log .bin directory contents after npm ci to understand why
pnpm binary is not found in subsequent CI steps.

* fix: ensure pnpm bin link exists after npm ci
npm ci sometimes doesn't create the .bin/pnpm symlink for
@pnpm/exe (observed on Linux CI). Manually create the symlink
if it's missing after npm ci completes.
This fixes the case where standalone=true with no explicit version
(relying on packageManager field) — pnpm self-update wouldn't run,
leaving .bin empty and pnpm not found on PATH.

* fix: add PNPM_HOME/bin to PATH for pnpm v11
pnpm v11 moved global binaries from PNPM_HOME to PNPM_HOME/bin.
Add the new bin subdirectory to PATH so that pnpm's global bin
directory check passes. This is backwards compatible — the extra
PATH entry is harmless for older pnpm versions.

* fix: add packages field to pnpm-workspace.yaml
pnpm v9 requires the packages field in pnpm-workspace.yaml.
Without it, `pnpm --version` fails with "packages field missing or empty".

When a project has both npm and pnpm, using pnpm/action-setup will result in an error: `Multiple versions of pnpm specified`.
The previous implementation was only meant to avoid the "ERR_PNPM_BAD_PM_VERSION" error, but it did not take into account the situation of multiple different package managers.
