Add question-reframing guidance to CLAUDE.md; commit accumulated project files

- CLAUDE.md: add "Question the question" and "One clarifying question" rules
  to Tone and Interaction — XY problem detection, false premise checks, and
  explicit reframe pattern before answering
- Add claude/ detail-file directory (topic docs referenced from CLAUDE.md)
- Add ABOUT.md, FUTURE.md
- Update memory/, scripts/, settings.yaml with accumulated session changes

+# skill: /end-session
+
+**Location:** `custom-claude-skills/skills/end-session/SKILL.md`
+
+## Purpose
+
+End-of-session wrap-up that combines session logging, CONTEXT.md update, and project doc refresh into a single command. Replaces the manual workflow of running `/log` then separately updating CONTEXT.md and project docs.
+
+## Usage
+
+```
+/end-session
+```
+
+No arguments. Reviews the full conversation history automatically.
+
+## How it works
+
+1. **Session log** (Phase 1): Creates `memory/log/YYYY-MM-DD.<HHMMSS>.md` with structured entries (Summary, Decisions, Gotchas, Open Questions, Key Context, Process Notes). Prunes old reflected logs per retention settings.
+2. **Context update** (Phase 2): Assesses what's in progress, updates CONTEXT.md index and `context/<topic>.md` detail files so the next session can resume without conversation history.
+3. **Doc refresh** (Phase 3): Updates FUTURE.md (new ideas), README.md (milestone table, scripts section), and CLAUDE.md (repo structure, conventions) -- only where this session actually changed something.
+4. **Summary** (Phase 4): Prints what was logged, what the next session should pick up, and which docs were updated.
+
+## Relationship to other skills
+
+- Subsumes `/log` -- no need to run `/log` separately when using `/end-session`
+- Does NOT include milestone reflection -- use `/reflect M<N>` separately when a milestone is complete
+- CONTEXT.md updates follow the same thin-index pattern documented in CLAUDE.md
+
+## Gotchas
+
+- Pre-gathers git log, git status, MEMORY.md, CONTEXT.md, FUTURE.md at skill load time -- if you made changes after invoking the skill, the pre-gathered data may be stale (but the skill can re-read files via tool calls)
+- `[topic]` tags on gotchas should match existing memory file topics for routing by `/reflect-logs`
