Issue for this PR
Closes #14453
Type of change
What does this PR do?
Make the web fetch tool's User-Agent be "OpenCode/${InstallationVersion}" by default and can be changed in the config. Before sending a request, it checks the domain's robots.txt and fails if it disallows the user-agent or has unofficial instructions to disallow AI input in general. Can optionally be configured to also block the request if it disallows AI training (if your LLM provider trains on your queries). Can also be disabled entirely in the config. robots.txt files are cached in RAM for up to 45 minutes, purged when more than 500 entries are present.
How did you verify your code works?
Asked Big Pickle to check his User-Agent and if he can access various websites.
