v1.9.0

Added

• Import identifier preservation guard: Post-merge validation detects when Morph's server-side model silently drops imported identifiers that were present in the original file. Blocks file write and returns actionable error with list of dropped identifiers. Covers Python, TypeScript/JavaScript, Go, Rust, Java, C/C++, and C# import statements.
• Python multi-line import handling: Parenthesized multi-line imports (from X import (\n Y,\n Z\n)) are normalized before extraction so identifiers inside paren blocks are correctly captured.
• TUI title for dropped-imports guard: tool.execute.after hook shows Morph: blocked (dropped imports) <file> when the guard triggers.
• 30 new tests: Full coverage for extractImportedIdentifiers (language-specific extraction) and findDroppedIdentifiers (roundtrip validation), including an end-to-end simulation of the exact scenario from GitHub issue #5.

Fixed

• Silent import data loss (#5): Morph's Fast Apply model can silently drop top-level import blocks when they fall outside the edit snippet's anchoring context. The new guard catches this before any file is written.
