Fix DeepReport repo-memory persistence: depth-2 paths silently dropped by file glob

[Copilot]

DeepReport's repo-memory (memory/deep-report branch) has been frozen at an April snapshot despite daily runs. The workflow prompt writes memory to /tmp/gh-aw/repo-memory/default/memory/deep-report/ — two folders deep — while its file-glob: ["*.md"] is a slashless pattern, which push_repo_memory compiles with matchSubfolderRoot and therefore matches only files exactly one folder deep. Every file was rejected at push time, and the rejection path logged core.info("No files to copy from artifact"), so the run looked like a clean no-op.

// slashless pattern => "[^/]+/[^/]*\.md"
globPatternToRegex("*.md", { matchSubfolderRoot: true })
  .test("deep-report/last_analysis_timestamp.md");         // true  — persisted
  .test("memory/deep-report/last_analysis_timestamp.md");  // false — silently skipped

Workflow fix

• .github/workflows/deep-report.md: memory paths moved to /tmp/gh-aw/repo-memory/default/deep-report/ (read, task-mining, and write steps), plus an explicit layout note instructing the agent to copy any legacy memory/deep-report/ files into the new location so history carries forward.
• Added *.json to file-glob — the task-mining step persists processed-discussions.json / extracted-tasks.json, which the *.md-only filter had also been dropping.

Silent-failure visibility

• push_repo_memory.cjs: when every artifact file is rejected by the glob, emit core.warning naming the rejected paths, the active FILE_GLOB_FILTER, and the depth rule, instead of an info-level no-op.

Prevention for other workflows

• repo_memory_prompt.go: the generated memory constraints now include a Required Layout bullet whenever any configured glob is slashless, so agents are told up front that root-level and deeply-nested files are discarded. Affects 24 recompiled lock files.
• Documented the same in reference/repo-memory.md; added a changeset.

Tests cover the new Go constraint helper, the constraints emitted by buildRepoMemoryPromptSection, and the deep-report path regression at the glob level.

• This layout constraint is only added in the single-memory default branch. A non-default single memory or a multi-memory configuration takes the return path at lines 115–181, whose template receives no glob constraints, so those slashless configurations remain undocumented and can still silently lose root/deep files. Propagate the requirement per memory through the multi-memory prompt as well.
