docs: document edit-wiki-page safe output tool and add to architecture tree

[Copilot]

edit-wiki-page was fully implemented (src/tools/edit_wiki_page.rs, wired into execute.rs and mcp.rs) but entirely absent from AGENTS.md — neither in the architecture tree nor the Safe Output Tools reference.

Changes

• Architecture tree: Added edit_wiki_page.rs to the src/tools/ listing in alphabetical order
• Safe Output Tools: Added #### edit-wiki-page section covering:
  • Agent parameters: path (no ..), content (≥10 chars), optional comment
  • Front matter config: wiki-name (required), wiki-project, path-prefix, title-prefix, comment
  • Explicit callout that wiki-name is required — execution fails without it

safe-outputs:
  edit-wiki-page:
    wiki-name: "MyProject.wiki"     # Required
    wiki-project: "OtherProject"    # Optional — defaults to current pipeline project
    path-prefix: "/agent-output"    # Optional — restricts write scope
    title-prefix: "[Agent] "        # Optional — prepended to page title segment
    comment: "Updated by agent"     # Optional — default commit comment

<issue_title>📝 Documentation drift detected — edit-wiki-page safe output tool undocumented</issue_title>
<issue_description>## Documentation Freshness Audit

The weekly documentation audit found the following inconsistencies between code and documentation:

Findings

Area	Issue	File(s)
Architecture tree	src/tools/edit_wiki_page.rs exists but is not listed in the directory tree	.github/copilot-instructions.md
Safe Output Tools	edit-wiki-page tool is fully implemented and wired up but has zero documentation	src/tools/edit_wiki_page.rs, src/execute.rs, src/mcp.rs

Details

1. Architecture tree missing edit_wiki_page.rs

The src/tools/ listing in the Architecture section shows:

├── tools/
│   ├── mod.rs
│   ├── create_pr.rs
│   ├── create_work_item.rs
│   ├── memory.rs
│   ├── missing_data.rs
│   ├── missing_tool.rs
│   ├── noop.rs
│   └── result.rs

But src/tools/edit_wiki_page.rs exists and is exported from src/tools/mod.rs (line 14: mod edit_wiki_page;, line 23: pub use edit_wiki_page::*;).

2. edit-wiki-page tool entirely absent from Safe Output Tools documentation

The tool is fully implemented:

• src/tools/edit_wiki_page.rs — agent params, config struct, executor
• src/execute.rs — handles "edit-wiki-page" in Stage 2 (lines 185–190)
• src/mcp.rs — exposes the tool via MCP server (lines 408–433)

The tool has the following interface (currently undocumented):

Agent parameters:

• path — Wiki page path to update (e.g. /Overview/Architecture). Must not contain ...
• content — Markdown content for the wiki page (at least 10 characters).
• comment (optional) — Commit comment; falls back to front matter config or "Updated by agent".

Configuration options (front matter):

safe-outputs:
  edit-wiki-page:
    wiki-name: "MyProject.wiki"     # Required — wiki identifier (name or GUID)
    wiki-project: "OtherProject"    # Optional — defaults to current project
    path-prefix: "/agent-output"    # Optional — prepended to agent-supplied path
    title-prefix: "[Agent] "        # Optional — prepended to the last path segment
    comment: "Updated by agent"     # Optional — default commit comment

Suggested Fixes

• Add edit_wiki_page.rs to the src/tools/ listing in the Architecture section of .github/copilot-instructions.md
• Add a new #### edit-wiki-page section under Safe Output Tools documenting agent parameters and front matter configuration options
• Note that wiki-name is required for execution (tool fails without it)
