/**

* Extract `:name`-style path placeholders from a URL string.
|
|
*
|
|
* A placeholder is `:` followed by one-or-more characters that are not `/`, `?`,
|
|
* `#`, or `:`. The `:` boundary means a placeholder ends where a literal colon
|
|
* starts in the same segment, e.g. `/tasks/:id:increment-importance` yields one
|
|
* placeholder `:id` and `:increment-importance` is literal text.
|
|
*
|
|
* Only `:` that sits at the start of a `/`-delimited segment counts — `/abc:def`
|
|
* has no placeholders. Returned names include the leading colon.
