chore(upstream): re-pin obra d884ae0 + Reasonix dce3b3a7 (non-breaking drift)

[christopherarter]

Summary

Addresses the upstream-drift issue (#4). Re-pins UPSTREAM.json after verifying both upstreams. No skill re-port required — this is a non-breaking re-pin.

Drift classification

obra/superpowers — 896224c4 → d884ae04

Upstream change	Port action
skills/using-superpowers/* (skill + 6 reference files) — heavy cleanup	None — using-superpowers is retired locally (see UPSTREAM.json retired); changes stay confined to that skill
skills/executing-plans/SKILL.md — dropped Gemini CLI from the subagent-platform list	None — our port already rewrote that Note to cite Reasonix's native task/wait/review, no Gemini mention exists
skills/writing-skills/SKILL.md — dropped Gemini tool-ref links	None — our port phrases the line as Platform spec → extending-reasonix, no Gemini links present
skills/brainstorming/visual-companion.md — dropped Gemini CLI run section	None — visual-companion.md is not shipped in this port

Reasonix main-v2 — f2a475a2 → dce3b3a70

⚠️ The PR message's claim of "no watched contract files changed" is inaccurate — substantial churn hit internal/tool/* and internal/skill/*. Verified it is non-breaking to our skills' surface:

Contract change	Impact on ported skills
internal/skill: +5 optional frontmatter keys (triggers, negative-triggers, auto-use, needs-fresh-data, cost); clipRunes → grapheme-cluster clipping for the 130-char index line	Optional metadata; our skill descriptions already front-load. ✅
internal/tool/builtin: +additive tools (read_only_skill, read_only_task, complete_step, delete_range, delete_symbol, move_file, code_index); refactor-only edits to bash/webfetch/glob/editfile/multiedit/readfile/writefile	Additive; every built-in tool name our skills name is unchanged at dce3b3a70. ✅
run_skill: fork_from schema field removed; runtime enforces continue_from/fork_from mutual exclusivity	We use neither continue_from nor fork_from in any skill body. ✅
read_only_skill (new plan-mode-safe entry point)	Additive; skills still cite run_skill/read_skill. ✅

Confirmed the registry at dce3b3a70 still contains every tool/skill our port depends on: bash, edit_file, multi_edit, read_file, write_file, glob, grep, ls, web_fetch, todo_write, run_skill, read_skill, task, explore, review, wait.

Bench-gate

• ✅ node bench/structural.mjs — 11/11 skills pass (obra + our own)
• ⏭️ node bench/bench.mjs Stage 2 (behavioral) — not re-run: no skill was re-ported, so BASELINE.json from the prior pin still stands and behavioral would only burn API budget testing an unchanged surface. Reasonix binary is not on PATH in this environment anyway.
• ✅ Manifest loads at the new pins (manifest.loadManifest).
