fix: align ET budget error strings with gh-aw detection patterns

[Copilot]

Bug Fix

What was the bug?

gh-aw's parse_mcp_gateway_log.cjs detects ET budget exhaustion by matching "exceeded" after "effective tokens", but AWF emitted "reached" — causing the specific-match regexes to silently miss AWF log lines. Only the generic 429 Too Many Requests pattern fired, which can't distinguish ET exhaustion from ordinary rate limits.

How did you fix it?

Renamed the event type and updated the error message in proxy-request.js to use "exceeded":

// Before
{ type: 'effective_tokens_limit_reached',
  message: `Maximum effective tokens reached (${total} / ${max}).` }

// After
{ type: 'effective_tokens_limit_exceeded',
  message: `Maximum effective tokens exceeded (${total} / ${max}).` }

Both logRequest call sites (HTTP and CONNECT paths) updated to emit effective_tokens_limit_exceeded. This makes all three AWF log sources — log event, JSON error body, and the raw log line — match the existing gh-aw regex /effective[\s_-]*tokens?.*exceeded/i with no changes required on the gh-aw side.

Pull request overview

This PR fixes effective-token (ET) budget exhaustion detection by aligning AWF’s emitted error type/message and log event name with the downstream gh-aw regex patterns that look for “effective tokens … exceeded”.

Changes:

• Renamed the structured error type from effective_tokens_limit_reached → effective_tokens_limit_exceeded.
• Updated the structured error message to use “exceeded” instead of “reached”.
• Updated the existing Jest test assertion to expect the new type.
