refactor(cli): centralize content registry building

Extract buildRegistryFromIndex and normalizePathKey from the CLI serve
command and the browser completions module into the shared
content-registry module. This ensures both paths produce identical
pathIndex/docContent, including the spark-injection pass that was
previously only applied in the CLI.
