Enhanced server.json validation (phase 1) (#636)
Added schema validation and support for exhaustive and more detailed
validation to existing validators. Added new `mcp-publisher validate`
command. No change to any existing tests or behavior other than the new
command.

## Motivation and Context

Many currently published servers fail schema validation. Of those that
pass, many have semantic/logical errors or other errors that make them
impossible to configure, or their configuration when applied doesn't
generate correct MCP server configuration (per their own documentation).

To address this, we need better tooling to validate servers and to
inform server publishers of errors, issues, and best practices in a way
that is clear and actionable, both during server development and at time
of publishing.

I have started a discussion about the broader topic:
https://github.com/modelcontextprotocol/registry/discussions/635

There is also a fairly detailed document describing the design,
architecture, implementation, future plans, etc. See [Enhanced
Validation Design](docs/explanations/proposed-enhanced-validation.md)

This PR is the first step in the process of improving validation. It
adds schema validation and updates all existing validators to use a new
model that allows them to track context and return rich and exhaustive
results. This has been done in a way that is backward compatible
(ValidateServerJSON is unchanged as are all existing validation unit
tests).

There is a new `mcp-publisher` command called `validate` that is
currenty the only place that schema validation and enhanced
(exhaustive/rich) validation results are exposed.

### Changes

Internal Validation improvements
- Schema validation has been implemented and is available as an option
in validation methods (defaults to off)
- Existing validators track the JSON path (context) of the attribute
they're evaluating, passing it to any child validators
- Existing validators are exhaustive (return all issues, not failing
fast on the first error)
- Existing validators return rich validation results, including:
  - type (schema, semantic, linter)
  - severity (error, warn, info)
  - path (JSON path to server.json element)
  - reference (to the schema element or rule that triggered the result)
  - message (currently the same as previous error message)

A new `validate` command has been added to `mcp-publisher` so publishers
can evaluate their server.json before publishing
- Includes new schema validation and previous semantic validation
- Shows full details of all issues encountered during validation

### Usage

Given a server.json that looks like this:

```json
{
  "$schema": "https://static.modelcontextprotocol.io/schemas/2025-09-29/server.schema.json",
  "name": "io.github.BobDickinson/registry",
  "description": "An MCP server that provides [describe what your server does]",
  "repository": {
    "url": "",
    "source": ""
  },
  "version": "=1.0.0",
  "packages": [
    {
      "registryType": "oci",
      "registryBaseUrl": "https://docker.io",
      "identifier": "registry",
      "version": "1.0.0",
      "transport": {
        "type": "sse"
      },
      "packageArguments": [
        {
          "type": "named",
          "name": "--mode",
          "description": "Operation mode",
          "format": "foo"
        }
      ],
      "environmentVariables": [
        {
          "description": "Your API key for the service",
          "isRequired": true,
          "format": "string",
          "isSecret": true,
          "name": "YOUR_API_KEY"
        }
      ]
    }
  ]
}
```

Run the command: 

`mcp-publisher validate server.json`

Which will produce the output:

```bash
❌ Validation failed with 5 issue(s):

1. [error] packages.0.packageArguments.0.format (schema)
   value must be one of "string", "number", "boolean", "filepath"
   Reference: #/definitions/Input/properties/format/enum from: [#/definitions/ServerDetail]/properties/packages/items/[#/definitions/Package]/properties/packageArguments/items/[#/definitions/Argument]/else/[#/definitions/NamedArgument]/allOf/0/[#/definitions/InputWithVariables]/allOf/0/[#/definitions/Input]/properties/format/enum

2. [error] packages.0.transport (schema)
   missing required fields: 'url'
   Reference: #/definitions/SseTransport/required from: [#/definitions/ServerDetail]/properties/packages/items/[#/definitions/Package]/properties/transport/else/else/[#/definitions/SseTransport]/required

3. [error] repository.url (schema)
   '' has invalid format 'uri'
   Reference: #/definitions/Repository/properties/url/format from: [#/definitions/ServerDetail]/properties/repository/[#/definitions/Repository]/properties/url/format

4. [error] version (semantic)
   version must be a specific version, not a range: "=1.0.0"
   Reference: version-looks-like-range

5. [error] packages[0].transport.url (semantic)
   url is required for sse transport type
   Reference: streamable-transport-url-required

Error: validation failed
```

Note in the results above:
- All errors contain the JSON path of the triggering element from
server.json.
- The first three errors are schema errors detected during schema
validation. The `Reference` provided contains an absolute path to the
schema rule that was violated, followed by the full schema path that
enforced that rule (with $ref redirect values substited and enclosed in
square brackets).
- The error messages provided by the existing semantic validators are
exactly the same as the previous error messages those validators
produced.

In the final solution we would remove semantic validators that are
redundant to schema validation (as in number 5 above). We have the
option to use the structured data produced by schema validation to
replace the generic schema validation message with a more descriptive
message if that is an issue (in particular, if the only argument for an
ad-hoc validator is that is produces a better/cleaner message, we would
just move that message creation code to the schema error result
formatter and special case it as opposed to having a redundant
validator).

### What's Next

If this general direction is supported and this PR is accepted, a fast
follow would include:

- Add new validators (infliuenced by observed issues) for both semantic
errors and best practices
- Require passing schema validation (in addition to improved semantic
validation) in order to publish
- Remove existing validation code that is redundant to schema validation
(ensuring error messages remain intelligible)
- Update validation client code and tests to handle the new rich return
types natively

### Issues

Schema validation requires embedding the `server.schema.json` file into
the validators package via `go:embed`, which is restricted from
embedding files outside of the package. For this reason we copy the
schema file into a schema subdir (via a prep target in the makefile) and
we .gitignore it. I tried cleaning up the copy in the make clean target,
but then the linter would complain about the embed target being missing
if it wasn't there during development. I also considered just checking
in the schema file and assuming a separate workflow for updating the
embedded schema file, but it's not clear what that workflow would be or
how it would be maintained. I'm open to a different approach, but the
schema file does need to be embedded somehow for schema validation to
work.

## How Has This Been Tested?
All existing validation tests pass, new tests implemented and all pass.

## Breaking Changes
No breaking changes, no behavior change except new `validate` command
