v3.13.0: subcommand flags removed (export-model, lint) but documentation still references them (breaking change)

[miguelmartens]

Description

In v3.13.0 the CLI flags for subcommands such as export-model and lint appear to have been removed, which breaks existing usage.

Previously these commands supported flags like:

mxlint-cli export-model \
  --input <path> \
  --output <path> \
  --appstore \
  --verbose

and for linting:

mxlint-cli lint \
  --input <path> \
  --rules <path>

However in v3.13.0 these flags no longer work. For example:

Error: unknown shorthand flag: 'i' in -i

When checking the CLI help output:

mxlint-cli export-model --help
mxlint-cli lint --help

both commands only expose --help, while only global flags remain:

Usage:
  mxlint-cli <subcommand> [flags]

Flags:
  -h, --help   help for <subcommand>

Global Flags:
      --config string   Path to config file (highest precedence)
  -v, --verbose         Turn on debug logs for all commands

Problem

It appears that PR #114 introduced a configuration-file driven approach (mxlint.yaml) and removed the CLI flags for subcommands.

However:

• The README documentation is not updated
• The Subcommands Reference still documents the CLI flags
• Both export-model and lint no longer expose any flags
• Existing workflows and CI pipelines relying on CLI flags now fail
• This introduces a breaking change in a minor release (v3.13.0)

Documentation still referencing flags:
https://github.com/mxlint/mxlint-cli/tree/v3.13.0?tab=readme-ov-file#subcommands-reference

Example CI usage that previously worked:

mxlint-cli export-model \
  --input $(Agent.BuildDirectory)/app \
  --output $(Agent.BuildDirectory)/exportmodel \
  --appstore \
  --verbose

Expected

One of the following:

1. Restore the CLI flags for backwards compatibility, or
2. Update the documentation (README + Subcommands Reference) and clearly document that configuration via mxlint.yaml is now required.

If the removal of flags is intentional, this should likely be documented as a breaking change.
