Pebble v0.0.3

Added

• Added unsigned macOS app and DMG build scripts, current-platform desktop build routing, macOS CI packaging, and tagged release DMG artifact uploads.
• Added the macOS .icns bundle icon required by Tauri's macOS application bundle.

Changed

• WebDAV restore now replaces local rules and Kanban cards/notes while merging account metadata from the backup, and restore previews disclose Kanban note counts.

Fixed

• Enabled the native macOS Keychain backend for local credential encryption.
• Made search over subject, sender, and recipient short fields case-insensitive for Latin text, and trigger a search index rebuild for older case-sensitive indexes.
• Indexed locally saved sent and queued outgoing messages so they appear in search results.
• Moved compose drafts, templates, and signatures out of frontend localStorage and into encrypted backend secure storage.
• Protected in-progress compose content from being overwritten when account, signature, or language-dependent defaults change.
• Added retry scheduling, exponential backoff, and a maximum attempt limit for pending mail operations.
• Aligned offline batch mail operations with single-message optimistic local commit behavior.
• Staged compose attachments through the backend so valid selected files no longer depend on fragile frontend path handling.
• Moved Kanban context notes out of frontend localStorage and into encrypted backend secure storage, with one-time legacy note migration.
• Hardened HTML email CSS sanitization against escaped url() tokens that could trigger remote loads in strict privacy mode.
• Prevented duplicate same-account sync workers by keeping the startup placeholder lock alive until the real worker replaces it.
• Report realtime restart failures back to the UI instead of silently accepting preference changes after all or part of sync restart failed.
