Backport upstream Go standard library changes to TinyGo's net package. Unmodified files (18) replaced directly from Go 1.26.2 source. Modified files (22) merged via 3-way diff, preserving all TinyGo netdev adaptations, TINYGO markers, and embedded-device constraints. Notable upstream changes included: - net/http: cookie handling improvements, fs enhancements, reverse proxy updates, chunked encoding fixes - net/http: ServeMux routing and pattern matching updates - net: IP parsing and MAC address handling improvements - Various doc link syntax modernization (e.g. [Dial], [Buffers]) TinyGo-only files (netdev.go, tlssock.go) unchanged. All TINYGO comment markers preserved.
