refactor(marmot): extract the incoming-sync policy from the CLI into commons

Context.syncIncoming carried real protocol policy — the NIP-59 gift-wrap
since-cursor rule (2-day lookback, advance only when events arrive),
per-group cursor bookkeeping, and the MIP-00 consumed-KeyPackage
rotation — that the Android app implements separately. Divergence there
silently drops DMs, so the policy now lives once in
commons/marmot/MarmotSyncPolicy with Cursors/Relays/drain/publish
injected, and the CLI Context wires itself in as a thin adapter.
Behavior is unchanged (the body moved verbatim, comments included).

Also resolves aliases from the per-account aliases.json in
Context.requireUserHex, so 'amy dm send bob ...' works with a local
alias — previously aliases.json was written but never read.

* Pull down everything needed to bring local Marmot state current:

*
* Incrementally advances the `since` cursors in [state] so the next run

*
* 1. NIP-59 gift wraps are published with a random-past `created_at`
* (see [com.vitorpamplona.quartz.utils.TimeUtils.randomWithTwoDays])
* so a newly-published wrap can trivially have `created_at` earlier
* than the last cursor we saw. To avoid silently dropping such wraps
* we always subtract a 2-day lookback window from the gift-wrap
* `since`, and dedup is handled inside [MarmotInboundProcessor].
* 2. We only advance the on-disk cursor when events actually arrive.
* Snapping an empty sync up to "now" on the first invocation would
* make every later `since` query skip any past-dated wrap or 445.
* The shared Marmot catch-up policy (gift-wrap 2-day lookback, per-group
* `since` cursors, MIP-00 consumed-KeyPackage rotation), wired to the
* CLI's pieces: [drain] for the one-shot subscription, [RunState] for the
* persisted cursors, and [publish] for the rotation replacements. The
* policy itself lives in `commons` ([MarmotSyncPolicy]) so the CLI and the
* Android app apply identical rules. Lazy so an anonymous run never
* materialises [marmot] (which would allocate the per-account stores).
