docs: mark reconstruction complete in CLAUDE.md and roadmap

The rebuild from the codegen-first OpenAPI/ogen design is finished; ongoing work
is incremental Bot API feature parity. Reframe the roadmap as a historical
record and drop the "active reconstruction" wording from CLAUDE.md.

 # Roadmap
 
-> Rebuild `github.com/gotd/botapi` from a codegen-first OpenAPI/ogen project into
-> a hand-written, MTProto-backed Bot API **library** that beats existing HTTP
-> Bot API clients on ergonomics and performance.
+> **The rebuild is complete.** This document is now a historical record of how
+> `github.com/gotd/botapi` was rebuilt from a codegen-first OpenAPI/ogen project
+> into a hand-written, MTProto-backed Bot API **library**. All phases below
+> landed on `main`; the library connects, serves updates, and exposes a broad
+> typed Bot API surface. Ongoing work is incremental feature parity, not
+> reconstruction; the `conformance_test.go` drift guard tracks coverage against
+> the published Bot API.
