1.49.0 (2026-08-21)

Features

• build: variants declare the frameworks they serve — one menu entry per framework (e9b0aca)
• integration: add Java (Spring Boot) as a full example-based variant (#270) (7ab67b4)
• integration: add Rust as a full example-based variant (#269) (716684b)
• integration: make Elixir a full example-based variant (#268) (86619ad)
• integration: make Go a full example-based variant (#267) (d2896b8)
• mcp-analytics: detect and instrument MCP TypeScript SDK v2 servers (c27f00a)
• metrics: orchestrator flow — verify the SDK before instrumenting (3dca124)
• metrics: orchestrator flow — verify the SDK before instrumenting (3545b0f)
• metrics: seed fans out one verify→instrument chain per service — monorepo-aware, parallel chains (223b229)
• metrics: seed picks the skill variant and hands it to tasks as input (50b9342)
• skills: add metrics skill family (posthog.metrics) (f57b7d9)

Bug Fixes

• integration-v2: make step prose platform-aware instead of web-shaped (9f35f18)
• metrics: report mirrors into a PostHog notebook like integration-v2 — no report file (6bbc198)
• metrics: report task writes posthog-metrics-report.md like replay-vision — outro has a file to show (bdd2a5e)
• metrics: seed manifest sweep is mechanical — one find per pattern, every ecosystem (956bbf0)
• metrics: seed maps every manifest ecosystem — a python worker inside an npm workspace gets its chain (45388be)
• metrics: tasks declare the metrics skill — the seed's pick pins the variant, not an install_skill call (5e06f15)
• metrics: verify-sdk at sol-medium, report on luna like the integration report (cb931da)
• rust: flush and shutdown are unconditional, not gated on an existing shutdown path (fe6959d)
• rust: flush and shutdown are unconditional, not gated on an existing shutdown path (47a0db5)

Reverts

• metrics: keep the five platform variants — tasks pull the matching one themselves (9a3e880)
