⚙️ [Maintenance]: Repository agents follow canonical MSX guidance (#422)

Repository agents now follow the canonical MSXOrg and PSModule guidance
for discovering repository context, framework documentation, and durable
memory without duplicating reusable process knowledge.

## Changed: Agent guidance follows the shared pointer model

The repository-level `AGENTS.md` now points contributors and agents to
the repository README, PSModule framework documentation, PSModule
memory, and MSXOrg-wide ways of working and coding standards. This keeps
shared process knowledge maintained in the canonical documentation while
retaining repository-specific context in the repository.

<summary>Technical details</summary>

- Replaced the generic context-resolution and documentation-standard
content in `AGENTS.md` with the thin-pointer structure defined by
[MSXOrg Agentic
Development](https://msxorg.github.io/docs/Ways-of-Working/Agentic-Development/).
- Matched the established guidance pattern used by
`PSModule/Template-PSModule`, `PSModule/docs`, and `PSModule/memory`.
- This is an agent/configuration-only change; no shipped module behavior
is changed.
- Standards and framework alignment:

| Changed surface | Standards checked | Framework docs checked | Result

- Issue convergence sweep: limited to this PR's documentation-only
scope; no additional open issues were fully satisfied by the diff.

+- [`README.md`](README.md) — what this repository is and its purpose as the
+  Process-PSModule framework.
+
+## PSModule Framework guidance
+
+Regarding repo structure, module source code, and how the Process-PSModule workflow
+works. For PSModule-specific build, layout, and process guidance:
+
+- [Process-PSModule docs](https://psmodule.github.io/docs/Modules/Process-PSModule/) —
+  repository structure, module anatomy, and the build/test/pack/publish pipeline.
+- [Repository defaults](https://psmodule.github.io/docs/Modules/Repository-Defaults/) —
+  the expected repository layout and required files.
+- [Standards](https://psmodule.github.io/docs/Modules/Standards/) — PowerShell module
+  coding standards.
+- [PSModule/memory](https://github.com/PSModule/memory) — durable cross-session agent
+  working memory for the PSModule organization.
+
+## Org-wide guidance
+
+For cross-cutting ways of working and standards:
+
+- [Agentic Development](https://msxorg.github.io/docs/Ways-of-Working/Agentic-Development/) —
+  how agents and humans collaborate in this ecosystem.
+- [Ways of Working](https://msxorg.github.io/docs/Ways-of-Working/) — contribution
+  workflow, branching, PRs, issues.
+- [Coding Standards](https://msxorg.github.io/docs/Coding-Standards/) — language-level
+  conventions.
+- [MSXOrg/memory](https://github.com/MSXOrg/memory) — durable agent working memory:
+  gotchas, knowledge, and agent role notes.
