Adds 4 (technically 5) new tools to the zed agent, corresponding to LSP
actions:
- `find_references`
- `goto_definition`
- `rename_symbol`
- `get_code_actions` and `apply_code_actions`
Notes:
- `rename_symbol` skips doing a `prepare_rename`. If there is nothing to
rename at the position, it will forward the error to the agent
- The code action tools are stateful. The state is stored in the
`get_code_actions` tool itself as a `PendingCodeActions`. It is not
passed into/out of subagents. Calling `apply_code_actions` without
calling `get_code_actions` first is an error, but I've never seen an
agent do this
Symbols are identified by:
- file name
- line number
- symbol
If there is no substring match on that line for the symbol text, it is
an error. If there are multiple, it chooses the first. This may not be
great if you have a line like: `fn convert(x: foo::Something) ->
bar::Something` - the second `Something` is a different symbol, but is
inacessible to these tools. Probably fine for now, but we can look into
improving
Release Notes:
- Added: New tools for the Zed Agent for interacting with language
servers
