/**
 * Workspace validation logic.
 *
 * This module validates a Quonfig workspace directory against the StoredConfig
 * schema. It can be used from both the oclif CLI (`qfg verify`) and the
 * standalone compiled binary (git pre-receive hook).
 *
 * Validation checks:
 *  - Valid JSON
 *  - Schema compliance (StoredConfigSchema from Zod)
 *  - Key matches filename
 *  - Key constraints (1-200 chars, no slashes, not "new", FS-safety floor)
 *  - Case-insensitive key uniqueness (no Foo/foo collisions)
 *  - Config type matches directory
 *  - Segment constraints (valueType=bool, sendToClientSdk=false)
 *  - Log level constraints (valueType=log_level)
 *  - Referential integrity (IN_SEG/NOT_IN_SEG reference existing segments)
 *  - schemaKey references existing schemas
 *  - Rule structure (criteria + value present)
 *  - Value type consistency
 *  - Weighted values non-empty and consistent
