dsh-file-mentions: Making file paths in DSH replies clickable and openable

dsh-file-mentions is a DSH web client plugin, developed by community maintainer a903067276-rgb. It transforms local paths wrapped in backticks within agent replies into clickable inline links, supporting opening with system default applications and revealing in file managers, and summarizes mentioned files as a chip list at the end of the turn. Home directory paths are available by default, while external drives require whitelist configuration. It can be installed via the command `dsh plugin --profile web add`, is licensed under MIT, and requires DSH web version 0.1.0-rc.6 or higher.
