Make --wrapstringinterpolation preserve the default

[Copilot]

The wrap rule wraps inside string interpolations (e.g. \(ShapeScript.version)), which doesn't reduce line length and degrades readability. The --wrapstringinterpolation preserve option already exists to prevent this, but wasn't the default.

// Before (default behavior): wraps at the `.` inside interpolation — unhelpful
"""
\(ShapeScript
    .version)
"""

// After (preserve is now default): leaves interpolation alone
"""
\(ShapeScript.version)
"""

• Changed default wrapStringInterpolation from .default to .preserve in Options.swift
• Updated two existing tests to explicitly pass .default so they continue testing the non-default wrapping behavior

• Fixes wrap rule suggests wrapping long strings inside interpolations #2643

Updated the help text in OptionDescriptor.swift to list "preserve" as the default, and regenerated Rules.md. Done in commit e9c1e6a.

Fixed. The testRedundantDefaultsInHelpOptionsDescriptions test was failing because the help text contained both "default" (as a value name) and (default) (as a marker). Removed the redundant (default) annotation from the help text and updated Rules.md.

@copilot, lol ok we obviously can't have the existing default value be the non-default value. Replace it with just true and false values, with the legacy default mapping to true and the legacy preserve value mapping to false. Default to false.

Replaced StringInterpolationWrapMode enum with a Bool property. true maps to the old default (wrap), false maps to the old preserve (don't wrap), defaulting to false. Legacy "default" and "preserve" string values are accepted as aliases.
