fix(skills): minimize Copilot telemetry intrinsic content

[Bill Berry (WilliamBerryiii)]

Description

Applied intrinsic-content minimization to the local, Azure fleet, and
agent-host relay OpenTelemetry Collector configurations.

• Normalized nonmatching span names, metric descriptions, and metric units to
  [redacted] while preserving the invoke_agent.* span-name family and
  metric names required by shipped consumers.
• Derived the protected span-name matcher set from shipped dashboard queries
  and added semantic regression tests for missing or consumer-breaking scrub
  rules.
• Updated runtime carrier expectations, the skill security model, and
  verification guidance to reflect behavior confirmed through OTLP/HTTP.

Success Indicators:

For detailed contribution requirements, see:

• Common Standards: docs/contributing/ai-artifacts-common.md - Shared standards for XML blocks, markdown quality, RFC 2119, validation, and testing
• Agents: docs/contributing/custom-agents.md - Agent configurations with tools and behavior patterns
• Prompts: docs/contributing/prompts.md - Workflow-specific guidance with template variables
• Instructions: docs/contributing/instructions.md - Technology-specific standards with glob patterns
• Skills: docs/contributing/skills.md - Task execution utilities with cross-platform scripts

Testing

• Passed 130 static skill tests with uv run --frozen pytest -m "not slow" -q.
• Passed 134 runtime carrier tests with
  uv run --frozen pytest -m slow tests/test_collector_carriers.py -q.
• Passed Ruff checking and formatting validation.
• Passed validation for all 77 Python-backed skills.
• Passed npm run validate:docs, including ESLint, type checking, 84 Jest
  tests, and 11 Mermaid tests.
• Passed npm run spell-check across 796 files.
• Passed branch-scoped link validation with zero broken links across 1,190
  Markdown files and 2,735 checked links.
• npm run validate:local completed all preceding lanes but failed in its
  repository-wide link lane on 17 unchanged files.
• npm run lint:md-links remained non-blocking for this branch because the
  failures were outside the nine-file diff; its changed-file mode passed.
• No manual testing was performed.

Checklist

Required Checks

• Documentation is updated (if applicable)
• Files follow existing naming conventions
• Changes are backwards compatible (if applicable)
• Tests added for new functionality (if applicable)

AI Artifact Contributions

• Used hve-builder review mode to review contribution
• Addressed all actionable findings from the hve-builder review
• Verified contribution follows common standards and type-specific requirements

Required Local Checks

The following local-safe validation commands must pass before merging:

• Local validation aggregate: npm run validate:local
• Documentation validation (if docs changed): npm run validate:docs
• Spell checking: npm run spell-check
• Link validation: npm run lint:md-links

Security Considerations

• This PR does not contain any sensitive or NDA information
• Any new dependencies have been reviewed for security issues (N/A - no dependency changes)
• Security-related scripts follow the principle of least privilege (N/A - no security script changes)

Additional Notes

Runtime confirmation covered the pinned OTLP/HTTP path. OTLP/gRPC and deployed
Azure behavior remained explicitly unverified.

The full-repository link lane reported failures in 17 unchanged files. The
branch-scoped run passed with zero broken links, so those failures were not
caused by this PR.
