Add shared B2 config JSON provider

[goanpeca]

Summary

• Add a shared b2-config: FileSystemProvider for bucket lifecycle, CORS, notifications, and bucketInfo JSON documents.
• Register bundled JSON schemas for each config kind and include those schema assets in the release contract.
• Require an opened b2-config snapshot plus a modal user confirmation before saves can mutate live bucket configuration, rejecting blind URI writes.
• Persist saves via B2 bucket update/notification APIs with optimistic revision checks, bounded remote timeouts, and indeterminate-timeout messaging.
• Harden notification handling by masking signing secrets and all custom headers, restoring masks only by stable rule identity, reconciling indeterminate saves, and serializing full-rule replacements through stale checks.
• Bound provider cache with close/account/TTL/size eviction, sliding expiry on access, minimal secret snapshots, descriptor-based path parsing, and schema/save-validation drift tests.

Fixes #103

Tests run

• npm run test:unit
• npm run check
• npm run compile
• npm test
• npm run contract:hash
• npm run assert:dist-assets

Follow-up notes

• Per-feature command/menu wiring remains out of scope for Shared edit-config-as-JSON mechanism (FileSystemProvider) for bucket settings #103 and can consume buildB2ConfigUri(...) in follow-up issues.

Pull request overview

This PR introduces a shared b2-config: virtual JSON editing surface for B2 bucket configuration (lifecycle, CORS, notifications, bucketInfo) via a VS Code FileSystemProvider, along with bundled JSON schemas for validation/completions and helper logic to mask/merge notification secrets.

Changes:

• Added B2ConfigFileSystemProvider and supporting JSON helper utilities (path parsing, stable fingerprinting, masking/merge, basic validation).
• Registered the provider during extension activation and added jsonValidation schema bindings for b2-config: URIs.
• Added unit tests for the JSON helper functions and introduced new JSON schema resources per config kind.
