Add {{filecontent}} support

[quolpr]

This will unlock such templates:

        template_selection = [[
I have the following content from {{filename}}:

{{filetype}}
{{filecontent}}

And I want to work on part of the code at line_start={{linestart}}, line_end={{lineend}}:

{{filetype}}
{{selection}}

Do this: {{command}}
]],
        template_rewrite = [[
I have the following content from {{filename}}:

{{filetype}}
{{filecontent}}

And I want modify this part of the code at line_start={{linestart}}, line_end={{lineend}}:

{{filetype}}
{{selection}}

Do this:{{command}}

Respond exclusively with the snippet that should replace the selection above.
DO NOT RESPOND WITH ANY TYPE OF COMMENTS, JUST THE CODE!!!
]],
        template_append = [[
I have the following content from {{filename}}:

{{filetype}}
{{filecontent}}

And I want modify this part of the code at line_start={{linestart}}, line_end={{lineend}}:

{{filetype}}
{{selection}}

Do this:{{command}}

Respond exclusively with the snippet that should be appended after the selection above.

        template_prepend = [[

This feature should essentially allow you to edit only a small part of the code, but provide more context for the LLM, right? I believe that’s what the chat sessions are designed for. They allow you to provide as much context as you want and allow you to provide a small piece of code that you wish to be edited.

Thank you very much, @quolpr, for your pull request. I decided to proceed with pull request #18 and have included an optional placeholder. An example of this has been added to the readme.

[quolpr]

@frankroeder hmm, but I also need linestart and linend 🤔 Also, what do you mean by

have included an optional placeholder

In my PR placeholder is optional too 🤔

[frankroeder]

Yes, your placeholder is also optional. Could you explain to me where linestart and lineend are coming from when you have a visual selection for which you trigger an interactive hook?
