Add installer to register tools as Claude Code slash commands

[bartTC]

Adds a curl-able installer that registers the markdown tools in this repo as user-level Claude Code slash commands under ~/.claude/commands/. After install, each tool is invoked as /<name> from any Claude Code session.

Three new files:

• install.sh — downloads the repo tarball, lists what it will install (with descriptions extracted live from each tool's frontmatter or first prose line), prompts for confirmation, then copies into ~/.claude/commands/. Re-running updates everything to the latest version.
• uninstall.sh — thin wrapper that runs install.sh in UNINSTALL=1 mode. Removes only files this installer placed; anything else under ~/.claude/commands/ is left alone.
• INSTALL.md — install/uninstall/options docs with sample output.

Why

Until now, using these tools meant copy-pasting markdown prompts into a session or symlinking by hand. A first-class installer makes the toolkit feel like the product it is:

• One command to install or update. curl … | bash, re-run to refresh.
• Discoverable. Tools show up in the / menu, namespaced (/voice:voice-of-william-gibson, /tutor:tutor-pydantic-v2-modeling) so they don't crowd the top level.
• Transparent. The installer prints the full list with descriptions before asking to proceed, and marks each entry + new or ↻ overwrite (update) so it's clear what will change.
• Reversible. A matching uninstall script removes the same set, surgically, without touching the user's own commands.

Single source of truth: the file list lives in install.sh; uninstall.sh is a 3-line wrapper, so there's no drift risk.

How to use

Install (or update):

curl -fsSL https://raw.githubusercontent.com/cppalliance/tools-public/master/install.sh | bash

Uninstall:

curl -fsSL https://raw.githubusercontent.com/cppalliance/tools-public/master/uninstall.sh | bash

Env knobs (set before the curl pipe):

Env var	Effect
INSTALL_YES=1	Skip the [y/N] confirmation
DEST=/path	Install elsewhere than ~/.claude/commands
LOCAL_SRC=/path	Use a local checkout instead of downloading
UNINSTALL=1	Run install.sh in uninstall mode
