chore(repo): normalise casing and trim comments

[mrcsin]

Summary

Two housekeeping changes that belong to no feature branch.

chore(repo): normalise path casing moves two completed plans from docs/ to Docs/ and fixes the COMDeviceSDK hint path in NtoLib.csproj from ..\resources\ to ..\Resources\, so the paths match the filesystem on a case-sensitive host.

style(opctreemanager): trim comments to the terse gate runs terse over the module. It reported 102 findings before, 21 after.

Type of change

• chore — tooling, build, docs, infrastructure

What the comment pass changed

• 17 <summary> blocks cut to three lines, with a pointer to Docs/known_issues/11-opc-pinpout-sibling-and-iconnect-connect.md or 05-opc-command-pin-connect-overload.md where the detail now lives
• 5 <para> blocks and 3 four-line comment essays in LinkCollectorTests removed
• 16 box-drawing banner rules deleted from ApplyDesiredSpecTests
• 35 em dashes and the arrow characters replaced with ASCII
• "CMD.Результат" in one test fixture became "CMD.Result"; nothing asserts on it

The 21 remaining findings are all in OpcTreeManagerFB.cs: Cyrillic inside [DisplayName], [Category], [Description] and the pin defaults. That is the operator-facing UI in the MasterSCADA property grid and cannot be ASCII. Before terse is wired into the build it needs either a rule that skips string literals and attribute arguments, or a per-file exclusion.

terse is not added to the repository in this PR; it was run manually.
