feat(electron): report custom URL protocol registrations

Expose static Electron protocol call facts through the shared application graph and existing CLI/MCP Evidence views. Preserve canonical case-insensitive scheme identity, original spellings, exact source provenance and explicit unknowns; keep registration success and runtime routing unproven.

Integration fixes also enforce module-only privileged API ownership, reuse the shared finding-key owner, and align the owning type documentation with the Evidence semantics. Validation and bounded real Obsidian CLI/MCP measurements are recorded in the PR.
