Refactor schema system: pass ParsedActionSchema in-memory instead of re-reading files

[curtisman]

Summary

Refactors the schema pipeline to pass already-loaded ParsedActionSchema objects in-memory instead of repeatedly reading .pas.json and .ts files from disk.

Changes

Manifest field naming

• Renames compiledSchemaFile → schemaFile (points to compiled .pas.json)
• Renames schemaFile → originalSchemaFile (points to .ts source for legacy code paths)
• Makes schema paths relative to the package directory
• Documents path resolution behavior in agentInterface.ts

Eliminate redundant file I/O

• enrichGrammarWithCheckedVariables now accepts ParsedActionSchema directly instead of loading from a file path
• Grammar generation callback (configureGrammarGeneration) returns ParsedActionSchema from the in-memory actionSchemaFileCache instead of resolving file paths on disk
• MCP server schema text is generated from parsed schema via generateSchemaTypeDefinition instead of reading .ts files from disk
• AgentSubSchemaInfo uses schemaText (generated from PAS) instead of schemaFilePath

New API

• Adds getSchemaInfoFromParsedSchema() to actionGrammar for extracting SchemaInfo from an in-memory ParsedActionSchema, with loadSchemaInfo refactored to delegate to it

Type safety

• Uses proper ParsedActionSchema typing in agent-cache instead of any
