Add a PostHog fake implementing event capture, feature flag evaluation, and user/group identification for AI agent testing. Endpoints: - POST /batch/ (capture, set, set_once, group_identify) - POST /flags/ (feature_enabled, get_feature_flag, get_all_flags) - POST /decide/ (legacy flag evaluation) - GET /api/feature_flag/local_evaluation/ (load_feature_flags) 19 contract tests verify all endpoints using the official PostHog Python SDK v7.9.

* feat: add PostHog analytics API fake service (#34) Add a PostHog fake implementing event capture, feature flag evaluation, and user/group identification for AI agent testing. Endpoints: - POST /batch/ (capture, set, set_once, group_identify) - POST /flags/ (feature_enabled, get_feature_flag, get_all_flags) - POST /decide/ (legacy flag evaluation) - GET /api/feature_flag/local_evaluation/ (load_feature_flags) 19 contract tests verify all endpoints using the official PostHog Python SDK v7.9. Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> * feat: add Todoist REST API v2 fake service Adds a stateful fake of the Todoist REST API v2 with 10 contract test modules covering tasks, projects, sections, labels, comments, subtasks, due dates, filtering, and cross-resource agent workflows. Generated by da-agent (multi-phase pipeline). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: add .mise.toml for todoist service Missing tool declaration caused CI to fail with "No such file or directory" because uv/python weren't installed by mise.

Summary
Add a PostHog fake service for testing AI agents that interact with analytics and feature flags without hitting the real PostHog API.
