feat(orchestrator): speak radio numbers, times and paths the ICAO way

pronounced() rewrites a radio text for speech in four passes: paths become file or folder with name and parent (/tmp as temp, ~/ as home), dates with or without a clock become a date-time group converted to Zulu, times become four ICAO digits with Zulu for UTC, and hex runs, version numbers and the remaining digits are spelled in NATO and ICAO words with Decimal between digits. Invalid dates and times stay as written; the displayed text is unchanged.

🎯 Fix: 90 %
💥 Break: 4 %
💸 Cost: 100 %
⏱️ Time: 100 %
🛡️ Security: 100 %
🏆 Score: 86
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %

+59. **Radio numbers and paths** (operator 2026-11-10): only the spoken line
+    changes, the displayed text stays as written. Digits are spoken in ICAO
+    words in Title Case, Ze-ro, One, Two, Tree, Fow-er, Fife, Six, Seven,
+    Eight, Ni-ner, and the NATO letters of hashes too (Alfa to Foxtrot);
+    this replaces the words of decisions 40 and 41. A time is four digits,
+    hour padded, no colon, seconds as two more digits; a UTC time ("08:15
+    UTC", "08:15Z", "0815Z", "08:15 Zulu") ends in one "Zulu", another zone
+    word follows the digits as written. A date with a time is the DTG
+    DDHHMM, "Zulu" when zoned, the full month name and the two-digit year
+    ("One Ze-ro One Fow-er Tree Ze-ro Zulu November Two Six"); an explicit
+    offset is converted to UTC first, no zone drops "Zulu", a date alone is
+    day, month and year. A dot between digits is "Decimal" and the "v" of a
+    version is dropped. An absolute, home or relative path (the relative one
+    with a slash and an extension on its last segment) is "file <name> in
+    <parent>" when the last segment has an extension (a dot and 1 to 5
+    alphanumerics), else "folder <name> in <parent>"; a trailing slash means
+    folder, "." is "dot", "-" and "_" a space, `tmp` at the root "temp", `~`
+    "home"; a URL is no path. Paths go first, then date-times, times and the
+    remaining digits and hashes. Rejected for paths: every segment with
+    "slash", the file name only, mapping to known repositories, not speaking
+    paths.
