fix(aws-lambda): surface sparticuz wedge as typed non-retryable error

Repeated Sandbox.Timedout chunks can leave @sparticuz/chromium
returning a falsy/empty path on subsequent invocations — warm
instances on the same execution environment never re-extract
chromium. The downstream puppeteer-core assertion about needing an
executablePath or channel buries the actionable cause; a cost-
analysis sweep took ~30 min to root-cause from that trace.

Guard the resolver: if mod.executablePath() returns a non-string,
empty string, or a path that does not exist on disk, throw a typed
ChromeBinaryUnavailableError whose message points at the recycle
remedy (env-var bump or redeploy). Add the error name to the three
NON_RETRYABLE lists so SFN short-circuits instead of burning four
15-min retries on a function that won't recover.

Same typed-error contract for the chrome-headless-shell fallback so
both sources fail consistently. Tests pin the wedge path (empty
string + non-existent file) and the carried metadata (source +
resolvedPath).
