feat: inline tab number editing in Item Number column

- Add inline tab input next to base part number when Tab column is hidden
- Tab column now visible by default for new users
- Tab input persists when configurations are expanded
- Consistent styling between hover and edit modes

+# Fix SOLIDWORKS Drawing Metadata Inheritance Multi-Agent Plan
+
+## Objective
+
+Resolve missing BR number/description/revision on SOLIDWORKS drawings by capturing drawing→model references, resolving PRP formulas from the referenced model, and syncing drawing metadata without overwriting drawings as the source of truth.
+
+## Agent Overview
+
+| Agent | Responsibility | Owns | Dependencies |
+|-------|---------------|------|--------------|
+| Agent 1 | TypeScript sync + references + logging | `src/lib/commands/handlers/*` | None |
+| Agent 2 | SolidWorks service PRP resolution | `solidworks-service/BluePLM.SolidWorksService/DocumentManagerAPI.cs` | None |
+
+## Shared Files
+
+| File | Owner | Rule |
+|------|-------|------|
+| None | — | No shared file edits expected |

+
+## Agent 1: TS Metadata + References
+
+### Prompt
+
+> Implement drawing metadata inheritance and reference extraction for BluePLM with enterprise-level code quality.
+>
+> **Scope:**
+> - Add drawing support to reference extraction in [`src/lib/commands/handlers/sync.ts`](bluePLM/src/lib/commands/handlers/sync.ts), [`src/lib/commands/handlers/checkin.ts`](bluePLM/src/lib/commands/handlers/checkin.ts), and [`src/lib/commands/handlers/extractReferences.ts`](bluePLM/src/lib/commands/handlers/extractReferences.ts)
+> - Update drawing metadata extraction in [`src/lib/commands/handlers/sync.ts`](bluePLM/src/lib/commands/handlers/sync.ts) to resolve PRP by reading the **first referenced model**
+> - Add logging for: PRP detection, parent reference chosen, missing parent, and inheritance outcome
+> - Ensure drawings remain source of truth (do not push DB values back into drawings)
+> - Document backfill path via **Sync SW Metadata** for existing drawings
+>
+> **Boundaries:**
+> - OWNS: `src/lib/commands/handlers/sync.ts`, `src/lib/commands/handlers/checkin.ts`, `src/lib/commands/handlers/extractReferences.ts`, `src/lib/commands/handlers/syncSwMetadata.ts`
+> - Do NOT modify: `solidworks-service/*`, database schema files
+>
+> **Quality Requirements:**
+> - Enterprise-level code quality and organization
+> - Proper TypeScript types (no `any`)
+> - Error handling and edge cases covered (missing parent, DM unavailable)
+> - Clean, readable, documented code
+>
+> **Deliverables:**
+> - Updated TS logic for drawing metadata and references
+> - Logs that allow debugging inheritance behavior
+> - Report in `AGENT1_REPORT.md`
+>
+> **When complete:** Run `npm run typecheck` and report results.

+### Boundary
+
+- **OWNS (exclusive write):** `src/lib/commands/handlers/sync.ts`, `src/lib/commands/handlers/checkin.ts`, `src/lib/commands/handlers/extractReferences.ts`, `src/lib/commands/handlers/syncSwMetadata.ts`
+- **READS (no modify):** `solidworks-service/BluePLM.SolidWorksService/DocumentManagerAPI.cs`
+
+### Tasks
+
+- [ ] Add `.slddrw` to reference extraction paths (sync/check-in/extractReferences)
+- [ ] Implement drawing metadata inheritance via first referenced model
+- [ ] Add logging for PRP detection + parent resolution + missing parent
+- [ ] Ensure Sync SW Metadata updates existing drawings without pushing DB → file
+
+### Deliverables
+
+- TS changes merged with clear logging and safe fallbacks

+
+## Agent 2: SolidWorks Service PRP Resolution
+
+### Prompt
+
+> Implement drawing PRP resolution in the SolidWorks Document Manager service with enterprise-level code quality.
+>
+> **Scope:**
+> - Update [`solidworks-service/BluePLM.SolidWorksService/DocumentManagerAPI.cs`](bluePLM/solidworks-service/BluePLM.SolidWorksService/DocumentManagerAPI.cs) to call `ReadDrawingReferencedModelProperties` when drawing properties are empty or PRP references are detected
+> - Use the **first referenced model** for deterministic inheritance
+> - Add concise diagnostic logging for the resolution path and missing parent
+>
+> **Boundaries:**
+> - OWNS: `solidworks-service/BluePLM.SolidWorksService/DocumentManagerAPI.cs`
+> - Do NOT modify: any TypeScript files
+>
+> **Quality Requirements:**
+> - Enterprise-level code quality and organization
+> - Error handling and edge cases covered
+> - Clean, readable, documented code
+>
+> **Deliverables:**
+> - Updated C# service with drawing PRP resolution
+> - Report in `AGENT2_REPORT.md`
+
+### Boundary
+
+- **OWNS (exclusive write):** `solidworks-service/BluePLM.SolidWorksService/DocumentManagerAPI.cs`
+- **READS (no modify):** `src/lib/commands/handlers/*`
+
+### Tasks
+
+- [ ] Detect PRP refs or empty drawing properties in `GetCustomProperties`
+- [ ] Resolve via `ReadDrawingReferencedModelProperties` using first reference
+- [ ] Log resolution path and missing parent scenarios
+
+### Deliverables
+
+- C# service enhancement for drawing property resolution
+
+---
+
+## Verification Checklist (Cross-Agent)
+
+- [ ] Create new part, assign BR number, description, revision
+- [ ] Check in part
+- [ ] Create drawing from part in SOLIDWORKS
+- [ ] Sync drawing to bluePLM
+- [ ] Verify drawing shows BR number, description, revision in file browser
+- [ ] Verify drawing shows metadata in details panel
+- [ ] Check `file_references` table has drawing→part relationship
+- [ ] Run Sync SW Metadata on an existing drawing and confirm DB updates
+- [ ] Test missing parent model (drawing references unsynced file) and confirm logs + no overwrite
