Add Unique filter method to Pipe
Add Shell method for running commands via the system shell
Adds ExecCommand(name, args...), which runs a command directly with
no parsing, holding the shared stdin/stdout/stderr/env/context/
error-handling logic.
Exec is now a thin wrapper that splits cmdLine with shell.Fields and
delegates to ExecCommand. A shell.Fields parse error is now surfaced
immediately via p.WithError, rather than only becoming visible once
the pipe is read; this is covered by
TestExec_SetsErrorImmediatelyOnInvalidCommandLineSyntax.
Shell runs cmdLine via the operating system's native shell (sh -c on
Unix-like systems, cmd /C on Windows, chosen via runtime.GOOS), by
calling ExecCommand directly with cmdLine as a single, completely
unmodified argument. This fixes the WithEnv/variable-expansion bug
described in #239, since the shell alone is responsible for parsing
and expansion, with no local re-interpretation of the command line.
Tested on both Linux and Windows.

This restores support for consumers still using Go 1.25. The previous bump to go 1.26.4 forced all consumers of this library to use Go 1.26 or newer.
The codebase does not use any Go 1.26-specific features, making the 1.26 language requirement unnecessary.
go1.25.11 contains the same critical security patches as go1.26.4 (fixing vulnerabilities in crypto/x509, net/textproto, and mime).
Go's toolchain auto-switching (introduced in Go 1.21) will automatically download and use go1.25.11 for developers working on this module if their local toolchain is older, ensuring they build with the secure version without forcing a major Go upgrade.
This makes govulncheck work even for users with go1.26.{0-3}
