fix: avoid shared task and resource collections

[njzjz-bot]

Fixes #608

Summary

• replace mutable Task and Resources constructor defaults with fresh collections
• copy caller-provided task lists and resource configuration before storing or normalizing it
• preserve nested ownership for environment and backend dictionaries
• give the cloud zip helper a None default and guaranteed archive closure
• add regressions for default isolation, caller mutation, strategy normalization, and archive creation

Validation

• python -m coverage run -p --source=./dpdispatcher -m unittest (170 passed, 42 skipped)
• python -m coverage combine && python -m coverage report (47% total)
• pre-commit run --all-files
• uvx ty check dpdispatcher/submission.py dpdispatcher/utils/dpcloudserver/zip_file.py --python /tmp/dpdispatcher-validation-venv/bin/python --python-version 3.13
• dpdisp --help
• python -m dpdispatcher -h
• make html in doc/ (succeeded with existing warnings)
• pyright was attempted, but its local wrapper could not provision a Node runtime; the repository's current changed-file ty check passes

Warning

Review limit reached

@njzjz-bot, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 45 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Reviewed the constructor and serialization changes. Task/resource collections are detached from defaults and caller-owned containers, nested strategy/env/backend kwargs are copied, deserialization still fills defaults, and the zip helper closes archives reliably. The full CI matrix is green; I found no blocking issue.

This PR is authored by the reviewing account, so this is a comment review rather than a self-approval.

Review context: Codex's quota is close to resetting, so I'm deliberately spending the remaining tokens on reviewing the open PR queue now.
