feat: Add lingma support (#2348)

* add lingma support

* fix

* fix context file

* Update CONTEXT_FILE path in test integration

* fix IntegrationOption.default

* fix IntegrationOption.defaultfix

* fix: address Copilot review feedback

- Add blank line after __future__ import (PEP 8)
- Remove trailing whitespace at end of lingma/__init__.py
- Bump integrations/catalog.json updated_at timestamp
- Add Lingma to supported agent list in README.md

* fix: address Copilot review feedback (round 4)

- Reword module docstring: Lingma is a brand-new skills-only integration
  with no prior command-mode history, so 'deprecated since v0.5.1'
  wording (copied from Trae) was misleading
- Remove Lingma from README CLI-tool check list: Lingma is IDE-based
  (requires_cli=False) and is explicitly skipped by specify init /
  specify check tool detection
