Note

Medium Risk
Medium risk because it upgrades the TypeScript compiler and @typescript-eslint tooling, which can change type-checking behavior and lint results across the codebase; a few small runtime code adjustments (binary uploads, stream chunk handling) may affect edge cases.

Overview
Upgrades TypeScript to 6.0.x, bumps @typescript-eslint to v8, and adds a temporary .npmrc legacy-peer-deps workaround to allow TS6 with current peer deps.

Modernizes tooling/config: switches gen:cdp from ts-node to tsx, updates ESLint config (parser options, rule tweaks/relaxations), and adjusts tsconfig.json path aliases.

Includes a few TS6-related code fixes: corrects ESTree traversal of ClassExpression.superClass, tightens typing for openid-client customFetch, ensures ArrayBuffer uploads use Uint8Array, guards against undefined IPC stream chunks, and updates a couple imports (./index and rrweb stylesheet path).
