- webclaw-llm: add explicit request + connect timeouts to the reqwest
client in every provider (anthropic, openai, ollama) with a shorter
timeout on the ollama health check, so a stalled provider fails fast.
- webclaw-llm: fix a panic when truncating a provider error body that
contains multibyte characters near the 500-char cut (char-safe take).
- webclaw-core: snap the endpoint-scan budget cut to a UTF-8 char
boundary so oversized scripts with non-ASCII content no longer panic.
- webclaw-core: rewrite js_literal_to_json to copy raw bytes instead of
`byte as char`, preserving multibyte UTF-8 in SvelteKit string values
rather than producing Latin-1 mojibake.
- webclaw-cli: have fire_webhook return its JoinHandle and await it at
the crawl/batch/batch-llm call sites, removing the fixed 500ms sleeps.
- webclaw-mcp: drop the up-front DNS pre-validation loop in batch that
aborted the whole request on one bad URL; the fetch layer already
applies the same SSRF guard per URL and reports per-URL errors.
- webclaw-fetch: include the port in the warmup homepage URL so hosts
on a non-default port are warmed correctly.
Adds regression tests for the UTF-8 endpoint-scan and SvelteKit cases.
