Add end-to-end quickstart test

[m3lixir]

Context

The README quickstart has been manually validated, but it is not yet covered by an automated end-to-end test.

Goal

Add an automated test that runs the core quickstart workflow from a clean temporary directory.

Workflow to cover

• chumdump init
• chumdump bait create --type canary
• chumdump dump build --profile website --count 1
• chumdump deploy ./public
• Create a simulated access log entry for the deployed bait file.
• chumdump watch --logs ./access.log
• chumdump bites
• chumdump report --format markdown --stdout

Acceptance criteria

• Test runs from a clean temporary directory.
• Test uses the installed CLI entry point or python -m chumdump.
• Test verifies one accessed bite is recorded.
• Test verifies the actor/crawler is identified as GPTBot.
• Test verifies the report includes Bite Type Summary and accessed: 1.
• Test is included in CI.

Notes

The GPTBot/1.0 user agent should remain a local fixture. The test should not depend on network access or any real crawler activity.
