* feat: add Trae IDE support as a new agent

Add Trae (https://www.trae.ai/) as a supported AI agent in spec-kit.
Trae is an IDE-based agent that uses .trae/rules/ directory for
project-level rules in Markdown format.

Changes across 9 files:
- src/specify_cli/__init__.py: Add trae to AGENT_CONFIG (IDE-based,
  .trae/ folder, rules subdir, no CLI required)
- src/specify_cli/extensions.py: Add trae to CommandRegistrar.AGENT_CONFIGS
  (.trae/rules, markdown format, .md extension)
- README.md: Add Trae to supported agents table, CLI examples, and
  --ai option description
- .github/workflows/scripts/create-release-packages.sh: Add trae to
  ALL_AGENTS array and build case statement
- .github/workflows/scripts/create-release-packages.ps1: Add trae to
  AllAgents array and switch statement
- .github/workflows/scripts/create-github-release.sh: Add trae template
  zip files to release assets
- scripts/bash/update-agent-context.sh: Add TRAE_FILE, trae case in
  update function, and auto-detect block
- scripts/powershell/update-agent-context.ps1: Add TRAE_FILE, ValidateSet
  entry, switch case, and auto-detect block
- tests/test_agent_config_consistency.py: Add 8 consistency tests for
  trae following established kimi/tabnine patterns

* fix: correct Generate-Commands parameter names for trae in PowerShell release script

Fix incorrect parameter names in the trae case of Build-Variant:
- -Format -> -Extension
- -ArgsToken -> -ArgFormat
- -OutDir -> -OutputDir

These now match the Generate-Commands function signature and all other
agent entries in the script.

* fix: add TRAE_FILE to update_all_existing_agents() for auto-detect support

Add missing update_if_new call for TRAE_FILE in the bash
update-agent-context.sh script's update_all_existing_agents()
function, matching the PowerShell implementation.

This ensures running the script without arguments will correctly
auto-detect and update existing Trae agent files.

* Add configuration for 'trae' in agents.py
