Add user-defined snippet support to the autocomplete plugin, including language-specific, global, .vscode, and .ecode project snippets. Support JSONC parsing, scopes, hot reload, source-aware ranking, exact prefix replacement, multi-cursor insertion, contextual indentation, variables, transforms, choices, linked placeholders, and tab navigation. Recognize .code-snippets files as JSON and preserve existing LSP snippet completion behavior. Refs SpartanJ/ecode#111
