Inlines the browser, session, and node registry management directly
into Agent. Updates CommandRunner to use Session and Registry directly,
and calls browser_tools.call without the ToolExecutor wrapper.
- Add support for triple-quoted strings (''' and """) in the tokenizer
and quote stripper.
- Avoid allocations in `stripQuotes` by returning slices.
- Optimize schema lookups using O(1) enum-based canonical resolution.
- Skip env var substitution if "$LP_" is not present in the string.
- Use `SlashCommand.globalSchemas()` instead of passing schemas around.
- Use `browser_tools.Action` enums for tool matching in Agent and Verifier.
- Optimize string substitution and quote stripping with early exits.
Unifies PandaScript syntax by replacing uppercase keywords with slash
commands (e.g., `/goto`, `/click`, `/fill`). Refactors the `Command`
representation to use a generic tool call structure backed by schemas.
BREAKING CHANGE: Uppercase PandaScript keywords (GOTO, CLICK, TYPE, etc.)
are no longer supported. All scripts must use slash commands.
- Replace `unreachable` with explicit error returns in Agent and Executor.
- Add `EvalResult.err` helper in `tools.zig` to simplify error paths.
- Improve error propagation in `SlashCommand` and `Recorder`.
- Rename `Self` to `Agent` for better clarity in function signatures.
- Use `SlashCommand.splitNameRest` for cleaner command handling.
- Centralize `max_hint_slots` constant and add assertions.
- Refactor `Spinner` thread management and rendering code.
- Cache environment variable names to improve completion performance.
- Refactor terminal styles into constants.
- Move `isAllUpper` to `string.zig` and `meta_names` to `SlashCommand.zig`.
- Align quoted string scanning logic with the slash command parser.
- Fix typo in REPL info message.
- Optimize Recorder to avoid unnecessary allocations.
- Simplify field type detection in SlashCommand using stringToEnum.
- Remove unused yellow ANSI constant in Terminal.
- Shorten log message in McpServer.
