added experimental /timeline/npub... route, this currently does
not correctly reload as contacts of that npub are lost onload.
other than that it seems to work well, but needs more testing.

ci/woodpecker/pr/woodpecker Pipeline was successful Details
ci/woodpecker/push/woodpecker Pipeline was successful Details
if difficulty-filter is set the subscription of the global feed
can filter only ids with 0-prefix to save bandwidth.

as there may not be many pow events within the last 24h, the
date range is now only enabled if there is no diffculty-filter
set so that the feed is not empty.

if this works as expected it could also only subscripe to
reactions and profile info with pow ids.

routes: use generic view containers
proof of concept to use generic view containers instead of specifc
functions to show and hide particular views.

a view has an identifier (path) which is used to subscribe to
relevant data. changing a view updates the history so that browser
back displays the last view. each view container has its own
scrollbar so that the scrolling position should be preserved when
changing back and forth between different views.

this change also removes CSS tabs in favor of view or overlays
such settings or write a new text note.

profile and notes deeplink use now native HTML anchors to improve
accessibility (copy/paste, open-in-new-tab, search engines).

instead of just adding 1 line for all replies to point to the

feed: less eager rendering
ci/woodpecker/pr/woodpecker Pipeline was successful Details
ci/woodpecker/push/woodpecker Pipeline was successful Details
before this change every new incoming text note called a render,
that filters, sorts and iterates all known text notes and creates
missing dom elements and appends into the right place.

this change throttles and debounces (both!) the render function,
that less checks have to be performed, especially on page load
when potentially 100s of events arrive within a short time.

it is important to throttle and debounce, else either the last call
is missed or no render is called while events are being received.

this change surfaced an error in recommend server that depended on
all known text notes already being rendered and inside the dom.
this function should probably be handled by render feed itself.

feed: dirty fix to show replies
now that nonce tag is always the first element in the tags list,
a bug surfaced that replies from nostrweb did not render anymore.

reason was that the code expected the first tag to be an e tag and
took its reply-id. this commit is a quick fix that takes the first
reply-id from the first e tag.

the proper way is a bit more complicated as nip-10 defines a
preferred and deprecated way.

this is a quick and dirty fix so that replies work with nip-13 pow
events, but nip-10 event tags should be properly supported but in
a later commit.

User can now navigate with browser back (with the expection of the

Not everything is supported in the detail view (yet) i.e reply and
stars are partially working (dont update visually), leaving this as
open bug. This should fix itself once only 1 render container is
used instead of different divs in the html for each view.
