[high] Malformed user regex crashes the entire scan

Malformed user regex crashes the entire scan

Severity	high
Kind	edge-case
Location	src/frameworks/synthetic-callers.ts → compileUserRules
Module	src/frameworks
Finding ID	f-4449ec

Failure scenario

Lines 344-345 pass configuration strings directly to new RegExp. A .codemaprc rule containing an invalid pattern such as "[" throws SyntaxError during Orchestrator.run, aborting codemap generation instead of producing a configuration error or safely rejecting the rule.

Suggested test

Call compileUserRules([{ caller: 'custom', name_patterns: ['['] }]) and assert the invalid rule is handled without an uncaught native SyntaxError.

How to work this issue

Open a Claude Code session in this repo and say
"work the dev-cli finding f-4449ec in src/frameworks/synthetic-callers.ts".

If this is not a real defect, close the issue with the false-positive label — dev-cli
records the fingerprint and will never raise it again. Closing it without that label marks the
finding fixed instead.
