* feat: add FilterPMGFromPath utility for PATH shim recursion prevention * feat: add FilterPMGFromEnv to filter PATH from env slices * feat: filter ~/.pmg/bin from PATH in proxy subprocess env * feat: add PathExport method to Shell interface for shim PATH integration * feat: add ShimManager for PATH shim install/remove lifecycle * feat: wire ShimManager into setup commands with --use-aliases fallback * refactor: add DefaultShimConfig helper to reduce setup boilerplate * fix: resolve real binary path to prevent shim double-invocation exec.CommandContext resolves the binary using the current process PATH, which still contains ~/.pmg/bin. This caused pmg to launch the shim instead of the real package manager, resulting in a second pmg instance with its own proxy — producing duplicate error messages and wasted work. ResolveRealBinary searches a filtered PATH (without ~/.pmg/bin) to find the real package manager binary before execution. * fix: resolve real binary in runner.Execute and expand path resolution tests Ensure guard mode and proxy skip paths also resolve through ResolveRealBinary to prevent infinite shim recursion. Add table-driven tests covering error cases, multi-binary PATH, and PATH restoration. * fix: handle error return values from os.Setenv and file Close calls Address errcheck lint failures: check os.Setenv returns in ResolveRealBinary, and check f.Close/tempFile.Close in ShimManager. * feat: auto-migrate shell aliases to PATH shims on setup install When running `pmg setup install`, detect existing shell aliases and automatically remove them before installing shims. Existing users get a seamless migration with no extra flags or commands needed. * fix: update E2E test to verify shim installation instead of alias RC file Replace the .pmg.rc file check with assertions that ~/.pmg/bin/ exists and contains executable shim scripts for npm and pip. * feat: add FilterPMGFromPath utility for PATH shim recursion prevention * feat: add FilterPMGFromEnv to filter PATH from env slices * feat: filter ~/.pmg/bin from PATH in proxy subprocess env * feat: add PathExport method to Shell interface for shim PATH integration * feat: add ShimManager for PATH shim install/remove lifecycle * feat: wire ShimManager into setup commands with --use-aliases fallback * refactor: add DefaultShimConfig helper to reduce setup boilerplate * fix: resolve real binary path to prevent shim double-invocation exec.CommandContext resolves the binary using the current process PATH, which still contains ~/.pmg/bin.

Remove --use-aliases flag and migration logic since both are always installed together. Update E2E to verify all shim scripts and alias RC file. * feat: address review feedback for shim implementation - Install both aliases and shims together for full coverage - Move homeDir resolution into NewDefaultShimManager (internal concern) - Add mutex to ResolveRealBinary to guard against concurrent PATH mutation - Use filepath.SplitList for platform-correct PATH splitting - Add ResolveRealBinary to runner.Execute and proxy flow to prevent shim recursion in all execution paths - Remove print side-effects from ShimManager.Remove - Update E2E to verify all shim scripts and alias RC file - Expand ResolveRealBinary tests with table-driven cases * fix: restore errcheck handling and add concurrency test for ResolveRealBinary - Restore proper defer with log.Warnf for PATH restoration in ResolveRealBinary - Restore errcheck handling for f.Close() and tempFile.Close() in ShimManager - Add explanatory comment for ResolveRealBinary call in proxy_flow - Add TestResolveRealBinaryConcurrent to verify mutex guards concurrent access * feat: skip shell integration on Windows with informative warning On Windows, pmg setup install now writes only the config file and prints a warning that shell aliases and PATH shims require WSL. * fix: PMG use pre-resolved binary path (#253) --------- Co-authored-by: Abhisek Datta <abhisek.datta@gmail.com>
