url: require 7+ digits to flag a match as a phone number

Browse Source 
AOSP's `Patterns.PHONE` matches any run of 3+ digits, so short codes,
ZIP codes, version strings, sport scores, room numbers — anything
numeric — surfaced as tappable `tel:` links on Android. iOS
`NSDataDetector` is locale-aware and quieter but can still emit short
matches in promotional text.

Filter both shims at the conventional 7-digit minimum: NANP local is 7
digits, all international numbers run 7+. Below that the match is
almost certainly not a dialable number. On Android `canonical_phone`
returns an empty string and `run_pattern` drops the record; on iOS the
detector block bails early before emitting the match.

Fixes user reports of `88773` and `75309` (a famous 7-digit run minus
its area code) being incorrectly flagged.
