feat: add install script and update release configuration

Adds install.sh script for easy installation of the latest release
binary via curl/wget on Linux (amd64/arm64). The script detects the
platform, downloads the appropriate release asset from GitHub, extracts
the 'reflow' binary, and installs it to /usr/local/bin using sudo.

Updates README.md to include the install script usage instructions and
replaces the dynamic Go version badge with a static one.

Updates .goreleaser.yml archive and release name templates to use
{{.Tag}} instead of {{.Version}} to include the 'v' prefix in artifact
names (e.g., reflow_v0.1.0_linux_amd64.tar.gz).

+### Install Script (Linux)
+
+You can install the latest version of Reflow using the following command. It automatically detects your architecture (amd64/arm64), downloads the correct release binary, and installs it to `/usr/local/bin`.
+
+**Note:** This requires `curl` or `wget`, `tar`, and `sudo` privileges to write to `/usr/local/bin`.
+
+```bash
+curl -sSL https://raw.githubusercontent.com/RevereInc/reflow/main/install.sh | sudo bash
+```
