liangshuo-1 c100ca049e feat(cmdutil): support @file for params and data (#724)
* feat(cmdutil): support @file for --params/--data (issue #705)

Inline JSON values for --params/--data are mangled by Windows
PowerShell 5's CommandLineToArgvW. Stdin (-) was the only escape
hatch but supports just one flag at a time.

Extend ResolveInput to accept @<path> (read JSON from a file) and
@@... (escape for a literal @-prefixed value), mirroring the
shortcuts framework's resolveInputFlags semantics. With this, both
--params and --data can be sourced from files in the same call,
sidestepping shell quoting on every platform.

- internal/cmdutil/resolve.go: add @path / @@ handling, trim file
  content like stdin does, error on empty path or empty file
- internal/cmdutil/resolve_test.go: cover file read, whitespace
  trim, missing file, empty path, empty content, @@ escape, plus
  ParseJSONMap / ParseOptionalBody integration through @file
- cmd/api/api.go, cmd/service/service.go: update --params/--data
  help text to mention @file

* refactor(cmdutil): route @file through fileio.FileIO abstraction

The first cut of @file support called os.ReadFile directly inside
ResolveInput, bypassing the codebase's fileio.FileIO abstraction
(SafeInputPath validation, pluggable provider). That diverged from
how every other file-reading path works: BuildFormdata for --file
uploads and the shortcuts framework's resolveInputFlags both go
through fileio.FileIO.Open with explicit fileio.ErrPathValidation
handling.

Re-route @file through the same path:

- ResolveInput, ParseJSONMap, ParseOptionalBody now take a
  fileio.FileIO; @path uses fileIO.Open which goes through
  SafeInputPath (control-char rejection, abs-path rejection,
  symlink-escape check) — same security posture as --file
- cmd/api and cmd/service callsites pass
  Factory.ResolveFileIO(ctx); the upload path now reuses the
  resolved fileIO instead of resolving twice
- Path-validation errors surface as
  `--params: invalid file path "...": ...` distinct from
  `--params: cannot read file "...": ...` for genuine I/O errors
- Nil fileIO with an @path returns a clear
  "file input (@path) is not available" error
- Tests use localfileio.LocalFileIO with TestChdir(t, dir),
  matching the existing fileupload_test.go pattern; absolute-path
  rejection and nil-fileIO are covered

This makes the feature behave identically under any FileIO
provider (including server mode) instead of being silently bound
to the local filesystem.
