First tool wired — `schema` (no input args, returns schema.v1 JSON
mirroring `kebab schema --json`). Establishes the per-tool module
pattern (crates/kebab-mcp/src/tools/<name>.rs) + error helper that maps
anyhow::Error to MCP CallToolResult.error with error.v1 content.
Dispatch pattern: manual dispatch — explicit `list_tools` + `call_tool`
overrides on `impl ServerHandler for KebabHandler` with a
`match request.name.as_ref()` arm per tool. No proc-macro magic.
Tasks 5-7 should add a new arm + new tools/<name>.rs following the same
pattern; also add a `Tool::new(...)` entry in `list_tools`.
API shapes confirmed from rmcp 1.6 source:
- Content = Annotated<RawContent>; text via `Content::text(s)`; pattern
match via `&content.raw` → `RawContent::Text(t)` → `t.text`
- CallToolResult::success(Vec<Content>) / ::error(Vec<Content>)
- ListToolsResult::with_all_items(Vec<Tool>)
- schema_for_empty_input() from rmcp::handler::server::common
