Release OWD Sync 0.1.4

[msinclair25]

What changed

• registers the owd-pair protocol handler before upstream plugin startup
• waits for upstream initialization before executing the pairing exchange
• strengthens the production bundle guard to enforce that order
• bumps the plugin, Obsidian compatibility map, installer guidance, and release links to 0.1.4
• records OWD Platform source commit 5406b5880613c716f5b398353da546160d483d59

Why

The dashboard could open a syntactically valid obsidian://owd-pair request
while the matching handler was not loaded in the opened vault. The earlier
startup order also delayed handler registration until after upstream
initialization.

User impact

BRAT testers receive a new immutable plugin release that recognizes the pairing
handoff as soon as OWD Sync loads. The dashboard still provides a command-based
manual fallback if Obsidian opens a vault where the plugin is disabled.

Validation

• sanitized source matches the reviewed monorepo adapter and guard
• pnpm check — formatting, lint, typecheck, 9 tests, build, production guards
• pnpm package — version-matched 0.1.4 ZIP and checksums
• every SHA-256 release checksum verifies
• built main.js is byte-for-byte identical to the monorepo candidate (9403c736df9642022a8255730a140df444f35e7e62d604828d7cc59420522f98)
• disposable Obsidian vault rehearsal opened the exact OWD pairing consent modal
