fix: handle spaces in working directory paths and MCP SDK type errors

[Scoteezy]

Summary

This PR fixes two issues:

1. Working directories with spaces weren't handled correctly, causing session file
   lookup failures
2. MCP SDK type instantiation errors (TS2589) breaking the build

Changes

Fix: Spaces in paths

Added space character to path sanitization regex to match Claude CLI's behavior for
session file lookup.

// Before
const projectId = resolve(workingDirectory).replace(/[\\\/\.:]/g, '-');

// After
const projectId = resolve(workingDirectory).replace(/[\\\/.: ]/g, '-');

Fix: MCP SDK TS2589 errors

Added @ts-expect-error directives to suppress "Type instantiation is excessively deep
and possibly infinite" errors caused by MCP SDK's complex generic types.
