Bind gstack as a first-tree source to gstack-repo-tree

[liuchao-001]

Summary

Onboards this repo as a source of the dedicated Context Tree at liuchao-001/gstack-repo-tree, produced by first-tree tree init + first-tree tree publish (CLI v0.5.2).

What lands here:

• AGENTS.md / CLAUDE.md — managed FIRST-TREE-SOURCE-INTEGRATION block agents read before every task. Points at the tree repo (https://github.com/liuchao-001/gstack-repo-tree.git), binding mode standalone-source, tree mode dedicated.
• WHITEPAPER.md — symlink to the locally-installed first-tree skill payload (.agents/skills/first-tree/SKILL.md).
• .gitignore — keeps .agents/skills/, .claude/skills/, and .first-tree/tmp/ out of source control (the skill payloads stay local; only the binding contract is committed).

Tree-side scaffold (NODE.md, members/, validate workflow, etc.) lives in the sibling repo — not here.

Test plan

• Confirm the managed FIRST-TREE-* block in AGENTS.md matches the live tree at https://github.com/liuchao-001/gstack-repo-tree.
• first-tree tree inspect from a fresh clone reports role: source and the correct tree URL.

📝 Walkthrough

Walkthrough

This PR establishes first-tree context tree integration for the gstack repository by adding git configuration rules, tree binding contracts, and content redirection. It configures ignored directories for temporary tree clones and managed skills, defines the binding metadata and workflow procedures in two documentation files, and converts WHITEPAPER.md to a symbolic link.

Changes

First-Tree Integration Setup

Layer / File(s)	Summary
Project structure configuration .gitignore	Git ignore rules exclude .first-tree/tmp/, .agents/skills/, and .claude/skills/ from version control.
Tree binding contracts and workflow procedures AGENTS.md, CLAUDE.md, WHITEPAPER.md	AGENTS.md and CLAUDE.md each add a first-tree managed binding block with tree repository metadata (tree-repo-name, tree-repo-url, binding-mode, entrypoint) and procedural guidance for updating/cloning the tree repository before tasks and coordinating PRs after tasks. WHITEPAPER.md becomes a symbolic link to .agents/skills/first-tree/SKILL.md.

🧹 Nitpick comments (1)

WHITEPAPER.md (1)

1-1: ⚡ Quick win

Symlink will be broken until first-tree is installed.

The symlink target .agents/skills/first-tree/SKILL.md won't exist in fresh clones because .agents/skills/ is gitignored. Users attempting to read WHITEPAPER.md before running first-tree tooling will encounter a broken link.

Consider adding a note in the main README or a placeholder comment explaining that WHITEPAPER.md requires first-tree installation to be readable.
