Fix markdown lint errors: add language specifiers and wrap bare URLs

[Copilot]

CI failing on MD040 (missing code fence languages) and MD034 (bare URLs). All fenced code blocks now have explicit language specifiers, all bare URLs wrapped in angle brackets.

Changes

MD040: Added text language to 13 code blocks

• sitrep-coordinator/SKILL.md (5 blocks): Authorization format, flow diagrams
• transformation-workflow/SKILL.md (1 block): Decision tree flowchart
• github-repository-architect/SKILL.md (6 blocks): Directory trees, CODEOWNERS format, branch rules, semver spec, commit conventions
• mcp-server-developer/SKILL.md (1 block): Test output example

MD034: Wrapped 11 bare URLs in angle brackets

• github-repository-architect/SKILL.md: Resources section (6 URLs)
• mcp-server-developer/SKILL.md: Resources section (5 URLs)

Example fix:

-```
+```text
Agent A → SITREP → Agent B → SITREP → Agent C

Original prompt

The repository currently has markdown lint errors (MD040), which indicate that fenced code blocks are missing language specifiers. Specifically:

1. In sitrep-coordinator/SKILL.md, at line 291:

   • Add a language specifier such as markdown, as the content within the code block appears to involve markdown formatting or examples. Change:

   Content here

   To:
   ```markdown
   # Content here
   

2. In transformation-workflow/SKILL.md, at line 646:

   • Determine the proper language for the code block, which could be plaintext (if it contains plain flowchart-like content) or another relevant language. For example:

   ```plaintext
   START: What's your primary need?
   ... (flowchart content)
   

These updates need to be applied for all affected files and lines, ensuring that every fenced code block explicitly specifies a language. This will fix the markdown lint errors and allow the CI pipeline to pass.
