feat: own the user-only /issue chat command + repo config

[mabry1985]

Stacked on #6 (write-ops). Base is feat/write-ops-complete; GitHub will retarget to main when #6 merges. Review the last commit for this PR's delta.

What

Brings the /issue chat control command into the plugin. Filing an issue is a write the model must not do autonomously, so — exactly like the core /goal — it's a user-only chat command, not an agent tool. The plugin owns it via protoAgent's new register_chat_command seam.

• gh_issue.py — ported, host-free /issue logic: flag parsing (--bug/--feature/--repo/--label/--dry-run), the gate-conformance check (same body rules the CI issue gate enforces — a substantive body + Problem/Motivation; bugs want repro; features want proposal/acceptance), and gh issue create. run_issue_command(rest, *, default_repo) is the seam entry.
• __init__.py — registers /issue when the host exposes register_chat_command, guarded by hasattr so an older host without the seam still loads the tools and just skips /issue (degrade-safe). The handler closes over the plugin's own configured default repo.
• manifest — adds github.default_repo + github.repos config (and settings fields). Repo resolution (no silent misrouting): explicit --repo > default_repo > first of repos > GITHUB_DEFAULT_REPO/GH_REPO env > error.

Host requirement

/issue needs the host's chat-command seam (protoAgent #1334, unreleased). Rather than hard-gate min_protoagent_version (which would block the tools on current hosts), the registration is hasattr-guarded so the plugin degrades gracefully: full tools everywhere, /issue only where the seam exists.

Tests

• test_gh_issue.py — parse/gate/file coverage (usage, no-repo, bad-repo, dry-run, files-and-returns-URL, default-repo routing, missing-sections block, gh-error surface).
• test_issue_command.py — register wiring: /issue registered when the seam is present, skipped (no crash) on a legacy host, and independent of the write gate.
• Gate green: ruff check ., ruff format --check ., pytest -q → 64 passed.

QA Audit — PR #7 | feat: own the user-only /issue chat command + repo config

VERDICT: WARN (CI still queued — non-blocking)

---

CI Status

• test: queued

Diff Review

• /issue registered via hasattr-guarded register_chat_command seam — safe degrade on legacy hosts
• gh_issue.py section detectors mirror CI gate regexes, ensuring gate-conformance before filing
• Repo resolution chain: explicit --repo > config default_repo > env > error — no silent misrouting
• Test suite covers parse/gate/file paths, 64 passed; no unresolved CodeRabbit threads

Observations

• LOW: clawpatch unavailable (repo not in project registry) — structural review limited to diff
• The _issue closure captures default_repo at registration time (startup config, no runtime mutation expected — fine)
