Matt Godbolt 65e4f302b7 URL serialization refactoring and Cypress test improvements (#8215)
## Summary
This PR makes URL serialization logic available to Node.js contexts
(like Cypress tests) and replaces a hard-coded 4812-character base64 URL
in tests with programmatically generated state. This builds on the
shared utilities refactoring from #8246.

### Changes

#### 1. Extract URL Serialization to Shared Module
**Problem:** URL serialization code depended on GoldenLayout's
browser-only ConfigMinifier, preventing Cypress spec files from
importing it (they load in Node.js before running in browser).

**Solution:** Created `shared/url-serialization.ts` with a
Node-compatible ConfigMinifier reimplementation.

**Technical Details:**
- Reimplemented GoldenLayout's ConfigMinifier without browser
dependencies
- Moved serialization functions (`serialiseState`, `deserialiseState`,
`risonify`, `unrisonify`) to shared module
- Moved minification functions (`minifyConfig`, `unminifyConfig`) to
shared module
- Updated `static/url.ts` to use shared module instead of GoldenLayout
- Added comprehensive test coverage in `test/url-serialization.ts`

**Files:**
- **New:** `shared/url-serialization.ts` (~279 lines)
- **Modified:** `static/url.ts` (removed ~30 lines, eliminated
GoldenLayout dependency)
- **New:** `test/url-serialization.ts` (~96 lines)

#### 2. Replace Hard-coded Cypress URL with Programmatic State
**Before:** A hard-coded 4812-character base64 URL containing state for
all panes
```typescript
cy.visit('http://localhost:10240/#z:OYLghAFBqd5TB8IAsQGMD2ATApgUWwEsAXTAJwBoiQIAzIgG...');
```

**After:** Programmatically generated state using
`buildKnownGoodState()` function
```typescript
const state = buildKnownGoodState();
const hash = serialiseState(state);
cy.visit(`http://localhost:10240/#${hash}`, {...});
```

**Benefits:**
- Human-readable, maintainable test state
- Programmatic generation from `PANE_DATA_MAP` keys
- Layout optimized with 8 panes per row
- Produces identical compressed URL format
- Much easier to add/modify panes in the future

#### 3. PANE_DATA_MAP Consistency Improvements
Updated `PANE_DATA_MAP` to use component names exactly as registered
with GoldenLayout:

**Key renames:**
- `preprocessor` → `pp`
- `llvmir` → `ir` 
- `pipeline` → `llvmOptPipelineView`
- `mir` → `rustmir`
- `hir` → `rusthir`
- `macro` → `rustmacroexp`
- `core` → `haskellCore`
- `stg` → `haskellStg`
- `cmm` → `haskellCmm`
- `dump` → `gccdump`
- `tree` → `gnatdebugtree`
- `debug` → `gnatdebug`

**Added panes:** `codeEditor`, `compiler`, `conformance`, `output` (were
missing from map)

**Re-enabled tests:**
- `yul` pane test (was commented out, now fixed)
- `clojuremacroexp` pane test (was commented out, now fixed)
- `cfg` pane test (had TODO, now removed)

**Why this matters:** The `buildKnownGoodState()` function uses
`Object.keys(PANE_DATA_MAP)` as the `componentName` property, so keys
must match the actual registered component names for GoldenLayout to
find them.

## Test Plan
- [x] All Cypress tests pass (confirmed by @mattgodbolt)
- [x] TypeScript compilation passes (`npm run ts-check`)
- [x] Linting passes (`npm run lint`)
- [x] URL serialization tests pass (3/3 tests)
- [x] Pre-commit hooks pass
- [x] Related vitest tests pass

## Dependencies
- Builds on #8246 (shared utilities refactoring - already merged)

Front-end unit tests

Tests here are super simple and use jsdom with a fake document to do quick checks on the front-end code.

For anything requiring a real browser, use the cypress tests in the cypress directory.
