…rderless UI

Major TUI rewrite from 2-panel + overlay to yazi-inspired design:
- Miller 3-column layout (parent/current/preview) with responsive ratios
- Tab system: t/T/W/1-9/[/] for multi-location and cross-project tabs
- Async preview engine with cache, context cancellation, syntax highlighting
- Borderless minimalist style with dim separators, no box borders
- Context-sensitive key hint bar (HUD) at bottom
- Mouse support: click parent=back, current=drill in, preview=forward
- Scroll wheel in all columns including MDL/NDSL content preview
- Soft line wrapping for preview content (no truncation)
- Slide animation on column transitions (width-based, 5 frames)
- Line numbers in preview pane with scroll percentage indicator
- Clipboard copy (y) from preview content
- Banner stripping for WARNING: and Connected to: lines

New files: app.go, tab.go, miller.go, column.go, preview.go, keys.go,
tabbar.go, statusbar.go, hintbar.go, icons.go
Deleted: model.go, layout.go, panels/ (6 files)

- Column widths now adapt to content (IdealWidth with lipgloss.Width)
- Parent capped at 30%, current at 35%, preview min 25%
- Soft line wrapping in MDL/NDSL preview (wrapVisual) instead of truncation
- Scroll calculations based on visual line count after wrapping
- Preview auto-populates on drill-in/go-back (no more "No preview")
- Animation slowed to 8 frames × 50ms = 400ms, proportional shift
- Output height clamped to prevent overflow affecting other columns
- Separator rendered as exact-height column of │ characters

Writes to ~/.mxcli/tui-debug.log when MXCLI_TUI_DEBUG=1.
Traces: key/mouse events, resize, navigation, preview requests,
column width calculations, animation state.

animTickMsg was not in the forwarding list in app.go Update(),
so animation frames never decremented and parent column stayed
permanently compressed.

Width-based animation caused all text to reflow simultaneously,
creating a dizzying effect. Replaced with clean instant column
shifts matching yazi's native behavior.

- buildDescribeCmd: add systemoverview → SHOW STRUCTURE DEPTH 2
- buildDescribeCmd: return "" for virtual container nodes (security,
  category, domainmodel, navigation, projectsecurity, navprofile)
- fetch(): show "Select a document to preview" when cmd is empty
- Add TestBuildDescribeCmd coverage for systemoverview and virtual nodes

fix(sdk/mpr): resolve module names through folder hierarchy in MPR v2

In MPR v2, documents (pages, microflows, etc.) live inside Projects$Folder
units, so their ContainerID points to a folder, not the module directly.
The previous single-level moduleMap[ContainerID] lookup always missed,
causing bson dump to fail with "page not found: Module.Name".

Add resolveModuleName() which walks the container hierarchy upward until
it finds a module unit, mirroring the catalog's findModuleID logic.
Fix both GetRawUnitByName and ListRawUnits.

- Add imagecollection → Images$ImageCollection mapping in GetRawUnitByName
  and ListRawUnits (reader_units.go) so bson dump --type imagecollection works
- Add imagecollection to inferBsonType() so NDSL preview mode can dump it
- Add imagecollection to buildDescribeCmd() no-MDL-command list (returns "")
  since DESCRIBE IMAGECOLLECTION has no MDL syntax; shows friendly placeholder
- Add TDD test cases for imagecollection in TestBuildDescribeCmd (RED→GREEN)

…t rule

Add executor handlers for image collection statements with module
lookup, duplicate detection, and hierarchy invalidation.

…E COLLECTION

Parse Image.Data, Format, and ID fields from BSON in parser_misc.go.
Write image data to /tmp/mxcli-preview/ and display IMAGE lines with
file paths in DESCRIBE output.

…nd security fix

- Add COLLECTION keyword to LSP completions
- Add visitor_imagecollection.go for CREATE/DROP IMAGE COLLECTION AST handling
- Fix writer_security.go to handle MaybeGeneralization in ReconcileMemberAccesses
- Add implementation plan doc

SetItems() resets cursor to 0; save and restore parentCursor/currentCursor
in navEntry so drillIn and goBack keep the selection visible.

- nanoflow: return empty (DESCRIBE NANOFLOW not implemented in executor)
- javaaction: fix syntax to DESCRIBE JAVA ACTION (two words, matching grammar)

Writer serializes image bytes under key 'Image' (Images$Image type),
but parser was looking for 'Data', so img.Data was always nil and
temp files were never written during DESCRIBE IMAGE COLLECTION.

…avaaction preview

1. drillIn(): save/restore actual item index (selectedIndex) instead of
   filtered-list cursor position so parent column highlights the correct
   item after SetItems clears the active filter.

2. fetch(): strip AS $$...$$ block from DESCRIBE JAVA ACTION output so
   the preview shows only the MDL signature, not the Java implementation.

Add 'javaaction' to inferBsonType() so Tab toggles to NDSL mode.
Add 'JavaActions$JavaAction' type prefix to GetRawUnitByName() so
bson dump can resolve javaaction by qualified name.

…tocol

Normalize \r\n and \r to \n in JavaAction documentation before
rendering. Add RETURN NAME, parameter descriptions, and ICON as
MDL comments in DESCRIBE JAVA ACTION output.
