Remove @ inline syntax for runtime imports, keep only {{#runtime-import}} macro

[Copilot]

The codebase supported two syntaxes for runtime file imports: the @./path inline syntax and the {{#runtime-import path}} macro. This removes the inline syntax, leaving only the macro syntax for consistency.

Changes

JavaScript runtime:

• Removed convertInlinesToMacros() function that translated @./path → {{#runtime-import path}}
• Simplified prompt processing pipeline from 4 steps to 3
• Removed 68 lines of inline syntax tests

Go compiler:

• Removed inline syntax pattern detection in containsRuntimeImports()
• Cleaned up test cases referencing @./ syntax

Workflows:

• Updated 2 workflows to use macro syntax:

  - @./agentics/code-simplifier.md
  + {{#runtime-import agentics/code-simplifier.md}}

Documentation:

• Removed inline syntax sections from templating and imports guides
• Updated all examples to use macro syntax exclusively
• Rewrote file-url-inlining.md to focus on runtime import macros

Migration

All runtime file imports now use the macro syntax:

<!-- Before -->
@./docs/standards.md
@./src/auth.go:45-75
@https://example.com/checklist.md

<!-- After -->
{{#runtime-import docs/standards.md}}
{{#runtime-import src/auth.go:45-75}}
{{#runtime-import https://example.com/checklist.md}}

Net impact: -449 lines, +92 lines across 14 files.

Original prompt

Remove the "@" syntax to import files and only support "runtime-import" instead.
