📝 WalkthroughWalkthroughAdds native semantic multi-block selection and Obsidian external note targets.

Align the integration with the published md-dragger API before merging.
The lockfile resolves md-dragger@2.0.1, but this PR imports selectBlocksInLineRanges, while that release does not export it. The integration also uses an unsupported per-view ux factory shape and unsupported externalTarget and commit option keys. Pin the engine revision that provides these APIs and update the dependency/lockfile, or adapt the integration to the public 2.0.1 API. Typechecking must pass before merge.

Scope the external-target CSS assertion to its own rule.
Line 18 allows any later CSS content to satisfy the accent-color check. The assertion can pass because .d-handle-core later contains var(--interactive-accent), even if .obsidian-dragger-external-target loses that declaration.
Use a rule-bounded assertion.

Split link delimiters before URI decoding.
decodeURIComponent(raw) converts %23 into # before subpath removal. A link such as Notes%23Archive then resolves as Notes, not Notes#Archive.
Remove raw | and # delimiters first. Decode the remaining path after that. Add a regression case in src/platform/obsidian/note-drop-target.spec.ts for an encoded literal #.

Continue scanning when a matching leaf has no CodeMirror view.
If getCodeMirrorView(markdownView) returns null, continue scanning matching leaves. Otherwise, obsidian-dragger.ts uses the vault persistence path even when a later leaf has a live view.

Important
This is a stacked draft depending on Ariestar/md-dragger#25. Local verification uses that engine checkout. Once #25 is merged and released on npm, this PR will update
md-draggerplus the lockfile and can become ready for review.Summary
How this extends issue #35
The existing multi-document commit contract supports dropping into another open editor by routing edits through document identity. The original request in #35 also asked to drop onto a linked page inside the current note or onto a page in the sidebar. Those elements are not editor documents, and their destination may not be open.
This PR adds that missing Obsidian adapter behavior. Engine PR Ariestar/md-dragger#25 supplies the generic selection, external-target, and async-commit hooks; all link, workspace, and vault knowledge remains in this plugin.
Behavior
.internal-linkanchors are supportedvault.processSafety and limitations
Destination persistence completes before source deletion. A failed destination write therefore leaves the source intact. Cross-file undo for an unopened destination cannot be atomic across both files.
Verification
Against the local checkout of Ariestar/md-dragger#25:
Manual Obsidian testing confirmed native multi-block selection, Live Preview internal-link drops, and File Explorer drops into unopened notes.
