Fix residual old-package references and rename SessionEventParserTest

The migration commit (da9ec9c) replaced com.github.copilot.sdk.events
with com.github.copilot.sdk.generated across all src/ files but missed
four non-source files that still referenced the old package:

1. jbang-example.java — updated imports from events.AssistantMessageEvent
   and events.SessionUsageInfoEvent to generated equivalents.

2. README.md — updated Quick Start imports to use generated package.

3. .github/copilot-instructions.md — updated Package Structure section
   to describe com.github.copilot.sdk.generated instead of the deleted
   com.github.copilot.sdk.events package.

4. config/spotbugs/spotbugs-exclude.xml — changed SpotBugs exclusion
   from com.github.copilot.sdk.events to com.github.copilot.sdk.generated,
   and updated the comment to match.

Also renamed SessionEventParserTest.java to SessionEventDeserializationTest.java
(class name updated to match) since the test no longer exercises the deleted
SessionEventParser class — it tests Jackson-native deserialization via
ObjectMapper.readValue(json, SessionEvent.class).

Build verified: 553 tests, 0 failures, BUILD SUCCESS.
were updated. mvn verify passes with 556 tests, 0 failures, 0 errors.
