[fuyongde]

Add iflow as a supported AI agent across all relevant configuration files, release scripts, and agent context scripts. Includes consistency tests following the same pattern as kimi/tabnine additions.

Description

Testing

• Tested locally with uv run specify --help
• Ran existing tests with uv sync && uv run pytest
• Tested with a sample project (if applicable)

AI Disclosure

• Extend release packaging + GitHub release scripts to build/publish iFlow template zips.
• Update agent context update scripts and add test coverage to ensure cross-surface consistency.

README.md:212

• The --ai option description is now out of sync with the actual supported agent keys derived from AGENT_CONFIG (it omits at least tabnine and trae, which are listed as supported elsewhere and appear in CLI help). Please update the list or point readers to specify --help/the Supported AI Agents table so documentation doesn’t drift as agents are added.

| `--ai`                 | Option   | AI assistant to use: `claude`, `gemini`, `copilot`, `cursor-agent`, `qwen`, `opencode`, `codex`, `windsurf`, `kilocode`, `auggie`, `roo`, `codebuddy`, `amp`, `shai`, `kiro-cli` (`kiro` alias), `agy`, `bob`, `qodercli`, `vibe`, `kimi`, `iflow`, `pi`, or `generic` (requires `--ai-commands-dir`) |
