fix: rename inputs/envs to input/env

[branchseer]

This PR standardizes the naming convention for task configuration fields by renaming plural forms to singular forms across the codebase.

Summary

Renamed configuration field names from plural to singular to improve consistency and clarity:

• inputs → input (for file input patterns in cache configuration)
• envs → env (for environment variables in cache configuration)

Key Changes

Configuration Schema Updates:

• Updated EnabledCacheConfig struct fields: envs: Option<Box<[Str]>> → env: Option<Box<[Str]>>
• Updated EnabledCacheConfig struct fields: inputs: Option<UserInputsConfig> → input: Option<UserInputsConfig>
• Updated TypeScript type definitions in run-config.ts to reflect the new field names
• Updated documentation comment for UserInputEntry to reference input array instead of inputs

Code Updates:

• Updated all references throughout the codebase to use the new field names
• Updated test cases and test fixtures to use input and env instead of inputs and envs
• Updated configuration deserialization and serialization logic
• Updated default values in UserTaskOptions::default()
• Updated synthetic task creation in lib.rs and main.rs

Documentation Updates:

• Updated task-cache.md documentation to reference input and env fields
• Updated wildcard-env-patterns.md to use env terminology
• Updated CLAUDE.md reference documentation
• Updated test snapshot descriptions and comments

Test Fixtures:

• Updated all vite-task.json fixture files to use input instead of inputs
• Updated all vite-task.json fixture files to use env instead of envs
• Updated test snapshot files and descriptions
• Updated e2e test configuration files

Implementation Details

• The change is applied consistently across all configuration layers (user config, resolved config, cache metadata)
• All serde deserialization/serialization updated to handle the new field names
• Comments and documentation updated to reflect singular naming convention
• Test names updated to match the new terminology (e.g., test_inputs_* → test_input_*)
