* Implement Headless REPL Architecture with WASM and Shell V2 UI - Add `HeadlessRepl` to `eldritch-wasm` for input buffering and parsing. - Create `headless-adapter.ts` for frontend WASM/WebSocket integration. - Implement `/shellv2` page with xterm.js. - Add `/shellv2/ws` dummy backend route. - Fix WASM build dependencies in `eldritch` libraries. Co-authored-by: KCarretto <16250309+KCarretto@users.noreply.github.com> * Implement Headless REPL with WASM, Shell V2 UI, Indentation, and Autocompletion - Add `HeadlessRepl` struct to `eldritch-wasm` with input buffering and fake library bindings for completion. - Create `HeadlessWasmAdapter` in frontend to bridge WASM and WebSocket. - Implement `/shellv2` page using xterm.js with support for indentation (Tab key) and autocompletion display. - Add dummy backend route `/shellv2/ws` in `tavern` for echo testing. - Update build scripts to deploy WASM artifacts to public assets. - Fix dependencies in `eldritch` libraries for WASM compatibility.

…ndling (#1816) * Implement enhanced Shell V2 features: completion dropdown, history search, and resizing - Frontend: - Added `xterm-addon-fit` for responsive terminal resizing. - Implemented shell state management (input buffer, cursor, history). - Added key bindings: Ctrl+C (reset), Ctrl+L (clear), Ctrl+A/E (home/end), Ctrl+U/W (delete line/word). - Implemented Tab completion with a custom dropdown UI overlay. - Implemented Ctrl+R for basic reverse history search. - Updated `HeadlessWasmAdapter` to support `reset()` and structured completion results. - Backend (`eldritch-wasm`): - Added `HeadlessRepl::reset()` to clear the internal buffer. - Updated `HeadlessRepl::complete()` to return `{ suggestions: [...], start: usize }` instead of a flat list, enabling correct inline replacement. - Added tests for reset and completion structure. - Rebuilt WASM artifacts with `fake_bindings` feature. Co-authored-by: KCarretto <16250309+KCarretto@users.noreply.github.com> * Fix Shell V2 cursor flicker, tab indent, and function termination - **Cursor Flicker:** Optimized `redrawLine` to avoid clearing the entire line (including prompt) and rewrite only the input buffer using `\r` + content + `\x1b[K`. Added fast-path logic in `onData` for appending characters or backspacing at the end of the line, bypassing `redrawLine` entirely for the most common typing scenarios. - **Tab Indenting:** Updated Tab handler to insert 4 spaces if the input buffer is empty or consists only of whitespace, enabling standard indentation behavior. - **Function Termination:** Ensured `state.prompt` is reset to `>>> ` when a command returns `"complete"` status, fixing an issue where the prompt would remain `.. ` after finishing a multi-line function definition.

- Fix duplicated prompt on Ctrl+L by using explicit ANSI clear+home sequence. - Implement multi-line history support by accumulating input blocks until complete. - Improve autocomplete: trigger on '.', allow typing while open, and fix looping index. - Refactor redrawLine to support multi-line buffers.

Adds a new page that isn't linked to yet, configures x term and uses the WASM interpreter for smart client-side REPL features, removing reliance on running REPL features on the agent and enabling a better non-interactive (no gRPC stream) shell experience.
