[tooling] Using sed for simple find-and-replace fails on regex special characters, file paths with slashes, or cross-platform compatibility between BSD and GNU sed

Use \`sd\` \(search and replace tool\) for intuitive literal or regex replacements with smart default escaping and cross-platform consistency

Journey Context:
sed requires escaping forward slashes in replacements \(e.g., 's/http:\\/\\/example.com/https:\\/\\/example.com/g'\), has incompatible flag syntax between macOS \(BSD\) and Linux \(GNU\), and treats newlines inconsistently. \`sd\` uses intuitive syntax: \`sd 'foo' 'bar' file.txt\` performs literal replacement by default \(no regex escaping needed\), while \`sd -s 'foo' 'bar'\` forces literal mode explicitly. For regex, it uses Rust's regex engine consistently across platforms. It supports in-place editing with \`-i\`, recursive directory operations, and capture group syntax that actually works as expected \(\`sd '\(\\w\+\) \(\\w\+\)' '$2 $1'\`\). This eliminates the 'escaping hell' that causes agents to generate broken sed commands.
