Duc-Tam Nguyen 3af26ae0e5 Rewrite the README and add a recorded demo
Rework the README into the house style: badges, a one-line pitch, an
anchor nav, a commands table, and dedicated sections for clone, pack, and
the native viewer. Every flag and default is checked against the current
binary so the docs match what kage actually does.

Add a demo recorded with ascii-gif. The tape clones example.com, packs it
to a ZIM and to a self-contained binary, and serves it back offline, so
the whole loop reads in one frame. It sits at the top of the README and on
the docs home.

While reviewing the docs, fix the output path everywhere: the default is
$HOME/data/kage, not the kage-out the pages claimed, including a few
fabricated 'done kage-out/...' lines. Document pack, open, and the native
viewer in the release notes.

Resuming a run Pick up an interrupted clone where it left off, and start fresh when you want to. 30

Cloning a large site can take a while, and runs get interrupted: you press Ctrl-C, your laptop sleeps, the network drops. kage is built to pick up where it left off.

How resume works

As it writes each page, kage records it in a small state file inside the mirror, at <host>/_kage/state.json. When a run ends, for any reason, that file holds the set of pages already written. Resume is on by default: the next time you run the same clone, kage loads the state and skips every page it already wrote, re-crawling only what is left.

kage clone example.com
# ... press Ctrl-C partway through ...
# interrupted; resume state saved (rerun to continue)

kage clone example.com
# resume: 137 pages already done

Ctrl-C is a clean stop: kage cancels in-flight renders, flushes the state file, and exits. You will not lose the pages already written.

Start fresh

To ignore any previous run and rebuild the mirror from scratch, delete the existing host folder first with --force:

kage clone example.com --force

This removes $HOME/data/kage/example.com/ before crawling, so nothing from a prior run carries over.

To run without reading or writing any resume state at all, for a strictly one-shot clone, use --no-resume:

kage clone example.com --no-resume
