feat(install): unified install.sh that prefers Homebrew

 ## Install
 
 ```sh
-brew install hotdata-dev/tap/cli        # Homebrew
-cargo install --path .                  # from source (requires Rust)
+curl --proto '=https' --tlsv1.2 -LsSf https://github.com/hotdata-dev/hotdata-cli/releases/latest/download/install.sh | sh
 ```
 
+The script uses Homebrew (`brew install hotdata-dev/tap/cli`) when `brew` is
+present and otherwise drops a prebuilt binary into `~/.hotdata/cli`. It then
+installs the agent skill for Claude Code and friends. Set `HOTDATA_NO_BREW=1`
+to skip Homebrew, `HOTDATA_NO_SKILLS=1` to skip the skill. To build from
+source instead: `cargo install --path .` (requires Rust).
+
 Or grab a binary from [Releases](https://github.com/hotdata-dev/hotdata-cli/releases).
 Stay current with `hotdata manage upgrade`; enable tab completion with
 `hotdata manage completions bash|zsh|fish`.

+#!/bin/sh
+# install.sh — one installer for Linux and macOS.
+#
+# If Homebrew is on the machine, install (or upgrade) through the tap so the
+# binary is managed by brew and `hotdata manage upgrade` follows suit.
+# Otherwise fall back to the cargo-dist shell installer, which drops a
+# prebuilt binary into ~/.hotdata/cli.
+#
+# Usage:
+#   curl --proto '=https' --tlsv1.2 -LsSf https://github.com/hotdata-dev/hotdata-cli/releases/latest/download/install.sh | sh
+#
+# After the binary lands, the agent skill is installed too (`hotdata manage
+# skills install`): it goes to ~/.agents/skills and is linked into ~/.claude
+# when that directory exists, so Claude Code picks it up with no extra step.
+#
+# Environment:
+#   HOTDATA_NO_BREW=1     skip Homebrew even when it is installed
+#   HOTDATA_NO_SKILLS=1   install the binary only, skip the agent skill
