* chore(deps): bump Rust and Dart dependencies

Bump Rust dependencies in library/ and patch/:
- comde: 0.2.3 → 0.3.1 (library), 0.2.3 → 0.3.0 (patch)
- zip: 0.6.4 → 3.0.0 (breaking: FileOptions → SimpleFileOptions)
- android_logger: 0.13.0 → 0.15.0
- mockall: 0.12.1 → 0.13.1
- serial_test: 2.0.0 → 3.2.0
- cbindgen: 0.24.0 → 0.28.0

Bump Dart dev dependency in shorebird_code_push/:
- ffigen: upper bound <17.0.0 → <19.0.0

Updated zip API usage (FileOptions → SimpleFileOptions) and
adjusted test assertion for changed error message.

Binary size impact (macOS release, arm64):
- libupdater.a: +83 KB (+0.28%)
- libupdater.dylib: +34 KB (+0.75%)

Closes #206, #271, #273.

* chore: add EOCD to cspell dictionary

The zip 3.0 crate changed its error message to reference "EOCD"
(End of Central Directory), which cspell doesn't recognize.
