feat: v0.3.0 Persistent + Z-Tiers + Input-Block

Browse Source 
Layer z_tiers (hud/normal/top), persistent windows, and input_block
routing (none/self/all) on top of v0.2.0's multi-active + layout-slot
model. Render iterates per-tier (hud->normal->top); input dispatch
iterates reverse (top->hud, within-tier reverse-open-order); modal
input_block='all' swallows misses. Persistent windows open at
register-time and are exempt from arg-less close() (so ESC and default
triggers cannot dismiss persistent toolbars/HUDs).

Adds chromeless=true opt (suppresses panel-lib's own decoration so
in-game HUD widgets like map-editor's toolbar/layers/palette can paint
their own visual style over the full widget bounds).

Adds public panel.point_in_any_panel(x, y) — module-side canvas-click
gate that returns true if (x, y) falls within any open panel's
bounds. Modules read input directly via engine.input.*; they can use
this helper to skip canvas-paint when the click landed on a panel
widget area.

# lib-core.panel
Generic overlay-panel framework. v0.2.0 supports multiple panels open at
the same time with 11 named layout-slot templates + custom-fn hook for
bespoke positioning. Handles input dispatch (mouse click + wheel,
edge-detected with reverse-open-order hit-test), renders titled panel
overlays, and supports a context-menu layer on top. Designed as the glue
layer between game modules and the engine render/input surfaces.
Generic overlay-panel framework. v0.3.0 layers **z-tiers** (hud / normal
/ top), **persistent windows**, and **input-block routing** (none / self
/ all) on top of v0.2.0's multi-active model with 11 named layout-slot
templates + custom-fn hook. Render iterates per-tier (hud → normal →
top); input dispatch iterates reverse (top → hud, within-tier reverse
open-order); modal `input_block="all"` swallows misses.
The single-active model from v0.1.1 is preserved as a backward-
compatibility shim — `panel.open(id)`, `panel.close()`, `panel.is_open()`
without an id-arg keep their old semantics.

## Scope (v0.2.0)
## Scope (v0.3.0)
v0.2.0 ships multi-active panels with layout-slot positioning,
preserving full backward-compatibility with v0.1.1's single-active
callers via shim semantics. The lib is the generic UI-Framework
substrate — domain-free per ADR-0001/ADR-0049, consumed by Display-
Libs (inventory-list-display, crafting-display, notify-display) and
modules (vagrant-skeleton).
v0.3.0 layers z-tiers + persistent + input-block on top of v0.2.0's
multi-active model, fully backward-compatible with v0.2.0 and v0.1.1
callers. The lib is the generic UI-Framework substrate — domain-free
per ADR-0001/ADR-0049, consumed by Display-Libs (inventory-list-

### Supported (v0.2.0)
### Supported (v0.3.0)
- Multi-active panels: multiple windows open simultaneously, each
rendered + hit-tested independently.
- 11 layout-slot templates (center, left, right, top, bottom, four
corners, left-half, right-half) for common positioning.
- Custom layout-fn hook `function(sw, sh) -> {x,y,w,h}` for bespoke
positioning (HUD elements, status displays, custom tool UIs).
- **Z-tiers**: render order hud → normal → top. Input dispatch reverse
(top → hud, within-tier reverse open-order).
- **Persistent windows**: `opts.persistent=true` auto-opens at register-
time. Arg-less `panel.close()` becomes no-op when focused is
persistent (so ESC/default-trigger cannot dismiss a persistent
toolbar/HUD). Explicit `panel.close(id)` still closes persistent.
- **Input-block routing**: `opts.input_block` = `"none"` (skip hit-test
entirely — HUD passes clicks through), `"self"` (hit-test own bounds;
miss falls through to next window), `"all"` (modal — hit-test self;
miss is swallowed, never reaches game-layer). Defaults per tier:
hud→none, normal→self, top→all.
- **Public `panel.point_in_any_panel(x, y)`**: helper for module-side
canvas-click logic — returns true if (x,y) falls within any open
panel's bounds. Useful for modules that read input directly via
`engine.input.*` and want to skip canvas-paint when the click landed
inside a panel widget.
- Multi-active panels: multiple windows open simultaneously (unchanged
from v0.2.0).
- 11 layout-slot templates + custom-fn hook (unchanged).

## v0.3.0 — Z-Tiers, Persistent, Input-Block
### Z-Tiers
Three rendering tiers, drawn bottom-to-top:
| Tier | Render order | Default `input_block` | Use-case |
|------|--------------|-----------------------|----------|
| `"hud"` | first (background) | `"none"` | HP-bars, status displays, world-overlays |
| `"normal"` | second | `"self"` | Toolbars, persistent panels, workbench windows |
| `"top"` | third (foreground) | `"all"` | Modal dialogs, blocking confirmations |
Within a tier, windows render in `open_order` (later-opened = drawn
later = on top of same-tier earlier-opened). Hit-test iterates reverse
z-tier (top → normal → hud); within tier reverse-open-order
(last-opened first). Unknown tier names raise a loud-error at
`panel.register` (typos surface immediately).
### Persistent Windows
```lua
panel.register("toolbar", widget, {
z_tier = "normal",
layout = "top",
persistent = true, -- open at register-time
input_block = "self",
})
```
`persistent=true` pushes the window onto `open_order` immediately and
makes `panel.close()` (no arg) a **no-op** when the window is focused.
Use this for in-game UI that must stay visible (toolbars, layer-pickers,
palettes, HUDs). The modder can still close it explicitly with
`panel.close(widget_id)`.
ESC-equivalent paths (default-trigger keys, arg-less `panel.close()`)
will NOT dismiss persistent panels. This protects users from
accidentally hiding their toolbar.
### Input-Block Routing (v0.3.0)
`opts.input_block` controls whether mouse events are absorbed:
| Value | Behavior |
|-------|----------|
| `"none"` | Window is never hit-tested. Mouse events pass through to lower windows. Use for HUD overlays. |
| `"self"` | Hit-test the window's own bounds. Clicks inside → widget; clicks outside → fall through to next window. Default for normal tier. |
| `"all"` | Modal. Hit-test self; clicks outside the window are swallowed (do not reach lower windows or the game-layer). Default for top tier. |
If any open window has `input_block="all"`, ALL outside-misses are
swallowed at the bottom of dispatch — this is the "modal block"
semantic. Game-layer code (canvas-paint, world-click) should consult
`panel.point_in_any_panel(x, y)` before reacting to clicks, since
panel-lib does not intercept clicks the module reads via `engine.input.*`
directly.
Tier-defaults: hud→`"none"`, normal→`"self"`, top→`"all"`.
### Test backdoors (v0.3.0 additions)
- `panel._test_get_render_order()` — array of widget_ids in the order
`M.render()` would iterate (per-tier, within-tier open-order).
- `panel._test_get_input_block(id)` — resolved input_block for a
registered window, or nil.
- `panel._test_get_persistent(id)` — persistent flag for a registered
window, or nil.
