Accept inline component definitions

[ghedwards]

Closes #49.

var msal = new component javaSettings='{"maven":["com.microsoft.azure:msal4j:1.23.1"]}' {
	function buildApp() { ... }
};

newComponentExpression required a path and a parenthesised argument list. The inline form has neither.

Grammar

The new alternative is NEW componentDeclaration — reusing the existing rule rather than restating its shape, so attributes, directives and members behave exactly as they do in a named component.

AST

CFAnonymousComponentExpression follows CFAnonymousFunctionExpression: a declaration statement hanging off an expression. The issue pointed at that precedent and it holds up — same problem, already solved once for function(){}.

The check that matters isn't the parse, it's the walk:

CFAnonymousComponentExpression
  CFCompDeclStatement
    CFFuncDeclStatement name=buildApp

Members reachable via decomposeScript(). Per CLAUDE.md, a green parse would have proved nothing here — this is exactly where #16 and #18 went wrong.

It regressed an existing fixture, and that was the interesting part

Adding the alternative broke parsing/cached_cf573.cfc, whose function carries cachedwithin=createTimeSpan(1,0,0,0) before its body.

That's the latent bug from #45 one rule over: simpleFunctionCall also had an optional trailing block, so the call swallowed the function's body. My alternative didn't create that — it only changed which way prediction fell.

Removing that body makes the fixture pass with its recorded tree untouched. I deliberately did not regenerate it: an unchanged expected file is the evidence that the removal restores correct behaviour rather than rationalising a new one. As with functionCall in #45, no visitor reads it — the ctx.body handling belongs to visitQualifiedFunctionCall, whose own rule keeps its own.

Worth noting for review order: #45 removes the same thing from functionCall. Different lines, so no textual conflict, but they're two halves of one problem.

Verification

• 313 cfparser tests, ./gradlew build, no expected file regenerated
• Differential harness 8 → 7, nothing newly broken
• CFLint 675 against a clean build
• components/inline_component_49.cfc fails with cfml.parsing/src/main stashed
