feat: add cc-clip ECC bundle

[ecc-tools]

Summary

Auto-generated ECC bundle from repository analysis.

What This Does

Merging this PR adds repo-local ECC artifacts for both Claude Code and Codex. The generated bundle captures repository patterns, Codex baseline config, and reusable workflow scaffolds derived from git history analysis.

Analysis Scope

• Commit history patterns and conventions
• Code architecture and structure
• Testing patterns and coverage
• Recurring workflows

Files

Path	Description
.claude/ecc-tools.json	ECC install manifest used for upgrades, repair, and uninstall.

.agents/skills/cc-clip/SKILL.md	Codex-facing copy of the generated repository skill.
.agents/skills/cc-clip/agents/openai.yaml	Codex skill metadata so the repo skill appears cleanly in the skill interface.
.claude/identity.json	Suggested identity.json baseline derived from repository conventions.
.codex/config.toml	Repo-local Codex MCP and multi-agent baseline aligned with ECC defaults.
.codex/AGENTS.md	Codex usage guide that points at the generated repo skill and workflow bundle.

Closing this. It is a regeneration of #99, which was reverted in #102, and it reintroduces the same blockers: the whole SKILL.md body is wrapped in a markdown code fence (so it renders as a code block instead of active guidance); it teaches incorrect Go 'relative imports' such as import ("internal/daemon") when the module is github.com/shunmei/cc-clip and Go modules do not support relative imports; openai.yaml sets allow_implicit_invocation: true, so that wrong guidance is injected without an explicit request; and git diff --check fails (trailing whitespace / missing final newline). If repo/ECC guidance is still wanted, it should be a small, human-maintained PR written from scratch with implicit invocation off — not a re-merge of the generated bundle.
