What do you want for trigger info?
The following pragma code will return all the data in the currently loaded
schema for all attached databases (table/index/trigger names). It creates a
new pragma called DATABASE_INFO (and table pragme_database_info) that returns
three columns: schema type

That is what I use now, together with the select as Hick mentioned.
An other version I played with is two indexes, one unique on (id,
ts_from) to find the last version if eol is not null and one unique on
(id, ts_eol) where eol = null to find the current active version of id.
Beware that in

max(ts_from) not only depends on every other record in the table, but is also
subject to change dependant on future inserts.

The max(). For the reason you identified: it would have to recalculate the
index values for all rows in the table every time any of the rows changed. You
CREATE TABLE test(
id INTEGER NOT NULL,
ts_from TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
ts_eol TEXT DEFAULT NULL
);
CREATE UNIQUE INDEX idx_test
ON test(id, max(ts_from), ts_eol)
WHERE ts_eol = NULL
;

Is this because max() is not
