feat(lsp): add cannonfile fragment schema and include field

[saturn-dbeal]

Summary

This PR adds support for cannonfile fragments - TOML files that are meant to be included from a main cannonfile and don't require top-level metadata like name and version.

Changes

1. Add include field to chainDefinitionSchema

include = [
    "tomls/settings.toml",
    "tomls/core.toml",
    "tomls/permissions.toml"
]

This field was already parsed by the CLI but was missing from the schema, causing IDE warnings.

2. Add cannonfileFragmentSchema

A new schema for included fragments that omits:

• name (required for publishing)
• version (required for publishing)
• preset (optional in both)
• include (only main cannonfile should include)
• privateSourceCode (only main cannonfile should define)
• description (only main cannonfile should define)
• keywords (only main cannonfile should define)
• deployers (only main cannonfile should define)

Fragments can contain all the same actions: deploy, invoke, clone, pull, var, router, diamond, etc.

3. Generate both schemas

• schema.json - Full cannonfile schema
• schema-fragment.json - Fragment schema for included files

Usage

IDEs/LSPs can now provide proper validation for:

• Full cannonfiles: Must have name and version, can have include
• Fragment files: Only actions, no metadata required

Example Fragment (tomls/core.toml)

[var.system_config]
core_package = "my-protocol-core:1.0.0"

[deploy.Core]
artifact = "Core"
args = ["<%= settings.owner %>"]

This fragment can be included from a main cannonfile without causing validation errors about missing name/version.

Draft PR - ready for review.

[saturn-dbeal]

Updated to also include the include field in the fragment schema, so fragments can include other fragments.

[saturn-dbeal]

Good call — extracted the shared actions into cannonfileActionsSchema and both the full schema and fragment schema now compose from it. ~76 lines removed.

[saturn-dbeal]

Addressed review feedback: deduplicated the schemas by extracting a shared cannonfileActionsSchema that both the full schema and fragment schema extend from. No more code duplication.

[saturn-dbeal]

Inline review comment addressed in 66411d0 — deduplicated the fragment and full schemas so the full schema extends the fragment.

Ready for re-review @dbeal-eth

tests will not pass due to PR being contributed from external, so merging with bypassed rues.
