chore: sync main — eyrie submodule, gitignore, display name test fix (#47)

* chore: update .gitignore with timestamped cache dirs

* feat: sync eyrie submodule + config updates for Xiaomi/MiniMax per-plan naming

* fix(cmd): align GatewayDisplayName test with eyrie per-plan naming refactor

* style: fix trailing newline

* chore(submodule): update eyrie to ea9747b (formatting)

* chore(submodule): update eyrie to 04b2cda (lint + test fixes)

* chore(submodule): update eyrie to merged main

* fix(readme): replace broken external hawk image with improved local SVG logo

- Removed unreliable openclipart.org hotlink (frequently failed to render on GitHub)
- Switched to assets/logo.svg with proper light/dark theme support via CSS prefers-color-scheme
- Simplified illustration for better scalability at small sizes while retaining character
- Added subtle adaptive frame, refined typography balance and spacing
- Removed duplicate heading for cleaner header
- Updated display width for the new logo

This makes the project branding reliably visible in both GitHub light and dark modes.

* fix(ci): update checkout-eyrie action to support submodule commits for sync PRs

- Clone using the exact commit from git ls-tree for external repos when present (for submodule updates in sync PRs)
- Falls back to branch clone otherwise
- This fixes the undefined symbols and missing go.mod in CI for sync PRs that update eyrie and xiaomi support

* fix(config): align xiaomi token plan env/resolve identifiers with eyrie per-plan naming
