DEVX-176: CI hygiene — docs fast-path, failure-notify scoping, post-merge cancel

Problem

devx CI has the same inefficiencies fixed in infra (OBL-INFRA-613/615/616): docs-only PRs run the full quality suite (~10 min), CI failures auto-create issues (noise — the user decided issues are for deploy failures only), and post-merge cancel-in-progress: true can kill a release mid-publish.

Approach

REQ-1: Docs-only PRs skip heavy validate steps (lint-all, unit tests, test-speed, translation check, security scan, workflow dry-run). Docs gate, spec validation, PR size, and auto-merge preconditions still run. Restricted to pull_request events.

REQ-2: Remove the failure-issue step from ci.yml validate job. Post-merge keeps failure notification (release/publish failures are deploy-pipeline events).

REQ-3: post-merge cancel-in-progress: false — a new push queues instead of killing an in-flight release/publish.

Test Plan

• make workflow-lint passes.
• Docs-only PR: quality steps skipped, docs gate + spec + size + merge run.
• Non-docs PR: unchanged behavior.

Deploy Plan

Workflow-only change; takes effect on merge. No release needed.

Rollback Plan

Revert the commit.

Acceptance Criteria

• REQ-1 implemented — early docs-only step + step-level if gates
• REQ-2 implemented — notify step removed from ci.yml only
• REQ-3 implemented — post-merge concurrency flipped
• make workflow-lint passes
