[Detector] rippling detector for phrase api tokens

Checklist:

[SyedAliHamad]

This PR introduces a new detector for Phrase Access Tokens.

Detection Strategy:

• Keyword Filtering: Efficiently scans for "phrase" keywords to identify relevant data chunks
• Pattern Matching: Uses regex to find 64-character hexadecimal tokens, typically prefixed with "phrase"
• Deduplication: Ensures each unique token is tested only once to prevent redundant API calls

Verification:
Live API Testing: Validates tokens against Phrase's /v2/projects endpoint. Uses the required Authorization: token header format

Response Handling:
200 OK: Token is valid and active
401/403: Token is invalid or expired
Other statuses: Reported as verification errors

Testing:
Includes comprehensive tests covering pattern matching, live API verification with both active and inactive tokens and edge cases.

I can't see pkg/engine/defaults/defaults.go being updated in this PR. Why is that?
Also, please resolve the conflicts.

LGTM!
Good Work on pattern test cases ❤️

Just one small non-blocking suggestion

Suggested change

	var tokens []string
	matches := keyPat.FindAllStringSubmatch(dataStr, -1)
	for _, match := range matches {
	token := match[1]
	if !slices.Contains(tokens, token) {
	tokens = append(tokens, token)
	}
	}
	var tokens = make(map[string]struct{})
	for _, match := range keyPat.FindAllStringSubmatch(dataStr, -1) {
	tokens[match[1]] = struct{}{}
	}
