Make data.sqlite upload explicit and optional

[benrfairless]

Description

Makes the upload of the local data.sqlite database explicit and optional. The database has always been included in the upload as a side effect of "upload everything in the directory", but nothing said so and there was no way to leave it out. Now the Uploading... line announces the database when it is included (Uploading 21.00 B (including data.sqlite)...), and a new --skip-data option uploads just the code. This wires up the database_path helper that was added in 2014 as groundwork for this feature but never used.

The timeout lookup is also simplified to Hash#fetch with identical behaviour (an explicit nil still disables the timeout), to keep execute within the repository's RuboCop metrics rather than loosening .rubocop_todo.yml.

Motivation and Context

Scrapers use data.sqlite to continue from the data they already have, so sending the local database with the run matters for incremental scraping - but it should be visible and skippable, since a large local database makes every upload slow.

How Has This Been Tested?

• Checked affected area manually on my own / staging system
• Ran automated tests on my own system
• Confirmed it passed the GitHub actions tests

Three new specs cover the announcement, the --skip-data exclusion (asserting the database bytes are absent from the multipart request body via WebMock) and the CLI option plumbing. All four CI jobs pass locally: bundle exec rspec (32 examples, 0 failures, coverage above the 90% SimpleCov floor), bundle exec rubocop (no offenses), bundle exec bundler-audit check --update and bundle exec rake build.

Approved - Makes sense to me. You may with to also add a --skip-spec (spec, coverage) or --skip-files=file,dir,file,*.bak as spec caused it to be too large in my previous attempts
