Add a csproj format handler to read and write <Version> tags in .NET project files.

• New src/formats/csproj.rs implementing the VersionFile trait
• Targets <Version> elements (capital V), ignoring Version attributes on <PackageReference> elements
• Only replaces the first <Version> tag (consistent with the xml handler behavior)
• Covers .csproj (C#), .fsproj (F#), and .vbproj (VB.NET) since they share the same structure
• Updated FileFormat enum, handler dispatch, schema, and tests

Config usage

{
  "package": [{
    "versionedFiles": [
      { "path": "src/MyApp/MyApp.csproj", "format": "csproj" }
    ]
  }]
}

Closes #30

Pull request overview

Adds a new csproj version-file format to FerrFlow so it can read/write .NET project versions from <Version> elements in MSBuild project files.

Changes:

• Introduces src/formats/csproj.rs implementing the VersionFile trait for <Version>…</Version> handling.
• Wires the new format into handler dispatch (get_handler) and updates config/schema to allow "csproj".
• Extends existing format dispatch tests to include the new enum variant.

File	Description
src/formats/mod.rs	Exposes the new module and dispatches FileFormat::Csproj to the new handler; expands handler dispatch tests.
src/formats/csproj.rs	Implements csproj read/write logic and adds unit tests for basic scenarios.
src/config.rs	Adds Csproj to the FileFormat enum for config serialization/deserialization.
schema/ferrflow.json	Extends the JSON Schema format enum with "csproj".

version_re matches the first <Version>…</Version> anywhere in the file and only when the opening tag has no attributes. This can (a) pick up <Version> elements outside <PropertyGroup> (e.g., a <PackageReference><Version>…</Version></PackageReference> pattern) and (b) fail to match common MSBuild patterns like <Version Condition="…">…</Version>. Consider parsing the XML and selecting the first <PropertyGroup>/<Version> element, or at least tighten the pattern to allow attributes while constraining the match to within a <PropertyGroup> block to avoid updating the wrong version.

write_version uses Regex::replace, which replaces all <Version> tags, but the PR description (and the tests in xml.rs) indicate only the first tag should be updated. Update the implementation to replace only the first match (e.g., replacen with a limit of 1 or manual slicing) and add an assertion/test that a second <Version> element remains unchanged.

[Copilot]

A new FileFormat::Csproj variant was added, but the CLI format prompt/parsing logic in this file is still hard-coded to [toml/json/xml/gradle/gomod/txt] and parse_file_format() doesn't map "csproj" (it currently falls back to Toml). This makes it impossible to select csproj via the interactive config flow and can silently misinterpret user input; update ALLOWED_FORMATS, the prompt text/error message, default_version_file(), and parse_file_format() to include csproj (and extend the existing file_format_serde_all_variants test to cover it).
