fix(symbian): ship native tile acceleration

[doodlewind]

Summary

• pin Pocket Figma to merged PocketJS 5bfaff7, retaining the GLES2/native tile bridge and adding final Nokia E7 physical top-row key mapping
• bump the independently installable Symbian package to 0.1.2
• replace the stale 0.1.0 device candidate that still routes tile work through QuickJS

Why

The final native-tile build from PR #4 was built and merged but never deployed to the E7. The device staging package remained 0.1.0. The native bridge sends TILESET entries directly from PAK storage to Rust/GLES2, avoiding per-tile QuickJS copies and decode work during pan and mip changes.

Validation

• bun run check:platforms
• bun run test:symbian-package: 3/3
• bun run test:symbian-smoke: 1/1, real guest build/boot and rotation state retention
• PSP/Vita package and touch tests: 12/12
• full pinned ARMv6 + GCCE + QuickJS + GLES2 SIS build
• receipt schema 3, version 0.1.2
• MTP upload and device readback byte-exact

Hardware acceptance

Accepted on the connected Nokia E7-00 / RM-626: Pocket Figma is fluid in real use, pan and zoom are responsive, and the Symbian controls work correctly.
