Add FormatConfig support for links notation formatting in all languages (C#, JavaScript, Rust, Python)

[konard]

Summary

This PR ensures that the formatter in all languages is configurable with special formatting options as requested in #155.

Changes Made

Rust Implementation (new in this PR):

• Added LiNo<T>::format_with_config() method for formatting individual links with configuration
• Added format_links_with_config() function for formatting link collections with configuration
• Implemented group_consecutive_links() helper for grouping consecutive same-ID links
• Added helper functions: escape_reference(), needs_parentheses(), format_value()
• Added 8 new integration tests verifying all formatting options

All 7 Formatting Options Now Supported Across All Languages

Option	C#	JavaScript	Python	Rust
lessParentheses / less_parentheses	✅	✅	✅	✅
maxLineLength / max_line_length	✅	✅	✅	✅
indentLongLines / indent_long_lines	✅	✅	✅	✅
maxInlineRefs / max_inline_refs	✅	✅	✅	✅
groupConsecutive / group_consecutive	✅	✅	✅	✅
indentString / indent_string	✅	✅	✅	✅
preferInline / prefer_inline	✅	✅	✅	✅

Example Usage

The formatter can now transform:

sequence: 1 2 3 4

Into indented format when configured (e.g., maxInlineRefs: 3 and preferInline: false):

sequence:
  1
  2
  3
  4

And group consecutive links:

(SetA a)
(SetA b)

Into:

SetA:
  a
  b

Test Plan

• All JavaScript tests pass (140 tests)
• All Python tests pass (138 tests)
• All C# tests pass (142 tests)
• All Rust tests pass (148 tests, including 8 new integration tests)
• Verify CI passes

✅ Double-Check Complete

I've verified all requirements from issue #155 are implemented correctly:

All 7 Formatting Options Confirmed Across All Languages

Option	C#	JavaScript	Python	Rust
lessParentheses / less_parentheses	✅	✅	✅	✅
maxLineLength / max_line_length	✅	✅	✅	✅
indentLongLines / indent_long_lines	✅	✅	✅	✅
maxInlineRefs / max_inline_refs	✅	✅	✅	✅
groupConsecutive / group_consecutive	✅	✅	✅	✅
indentString / indent_string	✅	✅	✅	✅
preferInline / prefer_inline	✅	✅	✅	✅

Issue Requirements Verified

1. ✅ Configurable formatter - All languages now support FormatConfig/FormatOptions
2. ✅ Formatting with/without parentheses - less_parentheses option
3. ✅ Inline vs indented format - prefer_inline + max_inline_refs + indent_long_lines
4. ✅ Format based on ref count - max_inline_refs triggers indentation
5. ✅ Format based on line length - max_line_length + indent_long_lines
6. ✅ Group consecutive links - group_consecutive option groups same-ID links
7. ✅ Custom indent string - indent_string option
8. ✅ All settings optional - All options have sensible defaults

Test Results

• Rust: 148 tests passed
• JavaScript: 140 tests passed
• Python: 138 tests passed (1 skipped)
• C#: 142 tests passed

Changes Made This Session

1. Resolved merge conflicts with main branch (linting/formatting updates)
2. Fixed Clippy warning (collapsible else-if)
3. Applied cargo fmt formatting

All CI checks are now passing ✅
