Add issue templates and cluster contribution guide

[linsalrob]

What changed

• add standard bug-report and feature-request templates
• add a structured issue form that gathers the scheduler, partitions/queues, QoS and accounting rules, resource limits, storage, software environment, and tested submission details needed to port an existing cluster profile
• add an inclusive contributor guide covering issue-first cluster contributions, branch-based profile adaptation, careful use of agentic AI, validation, and pull-request creation
• document Pawsey Setonix as a worked example and link the new guides from the main README

Why

Atavide lite maintains separate scheduler scripts because HPC systems differ in scheduler policy, resources, storage, and software setup. Complete, structured requests reduce guesswork when adapting deepthought_minion, deepthought_shortread, pawsey_minion, or pawsey_shortread.

User impact

Contributors now have clear entry points for bugs, features, and cluster support. New cluster requests should include enough operational detail to produce a reviewable and testable profile.

Validation

• parsed and structurally checked .github/ISSUE_TEMPLATE/cluster_support.yml
• git diff --check
• bash -n pawsey_lib/check_atavide_lite_env.sh
• python -m unittest discover -s tests -v (3 tests passed)

Pawsey queue and resource information was checked against Pawsey's current Running Jobs on Setonix and Job Scheduling documentation.
