feat: ✨ fully support sending and receiving GIFs

[clins1994]

Replacement for #141 after GitHub refused reopening the closed PR. This branch is pushed from a Beeper-network fork and includes the conflict-resolution merge from current main.

---

Fixes #90

Summary

• advertise GIF support to Matrix/Beeper capabilities
• send outbound Matrix/Beeper GIFs to LINE as image messages with GIF media metadata
• receive LINE animated images as Matrix fi.mau.gif video messages and fetch original OBS media when needed
• keep plain media uploads compatible with LINE OBS metadata without separately uploading thumbnails

Validation

• CGO_ENABLED=0 go test ./pkg ./pkg/connector ./pkg/connector/handlers ./pkg/e2ee ./pkg/line ./pkg/line/password ./pkg/line/secret
• docker compose build
• docker compose up --build -d and live bridge startup/log smoke check

See comments below for a QA list

Screenshots

Notes

Full local go test $(go list ./... | grep -v /ltsm) and go vet require libolm headers on the host; Docker build validates with olm-dev installed in the builder image.
