feat: add CodeFuse CLI usage parsing support

[Ed-Bg]

Summary

Adds CodeFuse CLI usage support across discovery, parsing, sync mapping, pricing/provider normalization, and web tool filters.

CodeFuse CLI can store usage in multiple local formats, so this PR imports:

• native CodeFuse project JSONL logs
• embedded Claude Code style JSONL logs under engine/cc/projects
• embedded Codex session JSONL logs under engine/codex/sessions
• ant_cc_*.json snapshot fallback files when no matching JSONL record exists

Changes

• Add codefuse to the core tool list, aggregator, parser exports, CLI watermark defaults, sync mapper, and web tool constants.
• Add CodeFuseParser for:
  • CodeFuse CC assistant usage rows
  • CodeFuse native assistant usage rows
  • embedded Codex token_count rows
  • tool call names without storing tool arguments
• Add CodeFuse discovery via CODEFUSE_HOME, AIUSAGE_CODEFUSE_PATH, legacy config, and default ~/.codefuse.
• Add snapshot fallback parsing for ant_cc_*.json, with JSONL de-duplication to avoid double-counting.
• Normalize routed model names such as glink/claude-opus-4-6 and antchat/claude-sonnet-4-6.
• Ignore non-assistant usage-looking rows and <synthetic> models.

Notes

The parser stores usage metrics, model/provider metadata, source file/cwd fields already used by aiusage, and tool call names. It does not store prompt text, completion text, or tool call arguments.

佬友你好，我很喜欢你做的这个工具，很有用，很漂亮，很感谢佬友的开发和分享！使用途中，我发现其中缺少了对code fuse的消耗统计支持，于是斗胆添加了一下，这是我第一次尝试参与开源项目和提PR，如果有任何不妥之处，恳请多多海涵和指正，谢谢！

Pull request overview

Adds first-class CodeFuse support to aiusage by wiring CodeFuse into discovery (CLI), parsing (core + CLI snapshot fallback), pricing/provider normalization, sync mapping behavior, and web UI tool filters.

Changes:

• Introduces CodeFuseParser in @aiusage/core to parse multiple CodeFuse/embedded formats (CC-like rows, native rows, embedded Codex token_count, and tool call names without arguments).
• Extends CLI discovery + parsing to find CodeFuse logs via env/config/default locations and to parse ant_cc_*.json snapshot fallbacks with JSONL de-duplication.
• Updates tool registries/constants, pricing prefix normalization, sync mapping rules, and adds comprehensive tests across core + CLI.

感谢 PR，@Ed-Bg。解析思路扎实，沿用了现有 Codex/Kiro 范式，快照与 JSONL 去重在增量和全量重解析下都没问题，测试也都通过。

我推了两个小 commit 到这个分支：

1. refactor：把重复的 normalizeCodeFuseModel / 时间戳解析抽到 core 复用；快照的 costSource 改为与解析器一致（基于 resolvePrice()）。
2. docs：README 和站点文档补上 CodeFuse。

构建和测试均已通过。没问题的话我就合并了。

没问题嘞，谢谢，辛苦维护啦！
