ADR-003 Use Single-Process Approach for Architecture Requests + Issue templates

[jhagberg]

Add GitHub Issue Templates and Labels

Summary

This PR adds GitHub integration to make it easy for people to ask architecture questions:

• Issue template for architecture-question
• Configuration for additional contact links
• Proposed label structure for workflow management

Proposed Labels

I suggest we create these labels manually after merging:

Core Labels (Required)

Label	Color	Description	Usage
architecture-question	#0E8A16 (green)	Questions for the architecture board	Auto-applied by template
high-impact	#D93F0B (red)	Affects all platforms	Requester or board adds
urgent	#B60205 (dark red)	Needs response within 48 hours	Requester adds (sparingly)
adr-needed	#5319E7 (purple)	Should be documented as ADR	Board adds during discussion

Optional Status Labels

Label	Color	Description	Usage
needs-decision	#FBCA04 (yellow)	Discussion ongoing, decision pending	Board workflow
waiting-for-feedback	#FEF2C0 (light yellow)	Waiting for requester response	Board workflow
resolved	#0E8A16 (green)	Question answered	Board closes issue

Optional Category Labels

Label	Color	Description
integration	#1D76DB (blue)	Integration between systems
standards	#1D76DB (blue)	Standards and specifications
security	#D93F0B (red)	Security-related
infrastructure	#BFD4F2 (light blue)	Hardware/storage/compute

Discussion question: Should we start with just the 4 core labels and add more as needed? Or create the full set upfront?

Blank Issues: Enabled ✅

Set to true to lower barrier. Anyone can open issue without template.

Rationale: Better to be welcoming than strict. We can require templates later if needed.

Question: Agree, or should we require template usage?

Discussion Questions for Reviewers

1. Label set: Start with 4 core labels or create all 11 upfront?
2. Blank issues: Keep enabled (true) or require template (false)?
3. Template tone: Too casual? Too formal? Just right?
4. Template fields: Missing anything important? Too many fields?
5. Contact links: Should we add Slack channel if we create one?
