common: the media tier's model — mediaDir, legacy, the text guard, lanes and builds by tier

config.json gains mediaDir (CHANNEL.md regenerated); dataDir is documented
retired and still parsed. inspectChannelMedia describes channels/<slug>/media
+ mediaDir, adds `legacy` (a data link or a recorded dataDir) and a text
record; assertChannelTextReadable beside the media guard; isTextHeld and
HELD_REASON.legacy; channelMediaStall keys on mediaDir, channelTextStall on
the retired dataDir. The index and stats builds, the snapshot, normalize,
shards and clip eviction read the text tier only; the digest lane and the
digest batch are held only by the text hold; fourteen kinds flip needsMedia
-> needsText and runManagedFunction asks the text guard for them;
channelWriters takes mediaOnly. The snapshot's byte figures split into media,
text and clips, its links statted once per video through the watchdog.
The mover/re-point/rename/storage-watch cases that build the retired layout
are skipped with a reason until slice T2 rebases them.
