fix: truncate long urls in concise network request output

[ZayanKhan-12]

What

Implements the existing // TODO truncate the URL in src/formatters/NetworkFormatter.ts: URLs in the concise one-line network request format are now capped at 150 characters, with the file's existing getSizeLimitedString helper appending the same ... <truncated> marker already used for request/response bodies.

Why

list_network_requests emits one concise line per request, so a single page with a few data: URLs (which can be tens of kilobytes each) can blow up the tool output by orders of magnitude. Truncating in the concise format keeps list output token-friendly while losing nothing that matters for identifying a request.

Scope is deliberately narrow — only convertNetworkRequestConciseToString changes:

• the detailed view (## Request <url> heading) still shows the full URL, and
• toJSON() / structured content still carries the full URL,

so nothing that needs the complete URL is affected. (Concise redirect-chain lines inside the detailed view use the same function and are truncated too, which keeps that list compact as well.)

Limit rationale

150 characters keeps origin + path + the start of the query string intact for virtually all real-world URLs (typical URLs are well under 100 characters), while capping pathological data:/blob payloads. It reuses the existing getSizeLimitedString pattern with a new URL_CONTEXT_SIZE_LIMIT constant next to BODY_CONTEXT_SIZE_LIMIT.

Before / after

Before:

reqid=12 GET data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA... (10,000+ more chars) ...5CYII= [200]

After:

reqid=12 GET data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA...(150 chars total)... <truncated> [200]

Short URLs are unchanged.

Testing

• npm run build — pass
• npm run test:no-build — pass (all tests, exit 0)
• npm run check-format — pass (eslint + prettier)

Added three cases to tests/formatters/NetworkFormatter.test.ts:

• long URL is truncated at 150 chars with the ... <truncated> marker (and toJSON() keeps the full URL),
• data: URL is truncated,
• a URL exactly at the limit is left untouched.

No existing snapshots changed.
