Two UX fixes surfaced by first real-user use:
1. cog_spending / cog_revenue / cog_geographic_rollup now accept either
a character vector OR a data.frame with a canonical_govid column
(e.g. output of cog_gov_search() or cog_find_peers()). Shared
.coerce_govid_input() helper in session.R. This lets the natural
pipe work:
cog_gov_search('MIAMI', state='FL', type='city') |>
cog_spending(years=2022, category='Police')
cog_peer_compare already accepted a data.frame for the peer arg;
behavior there is unchanged.
2. .check_govids_in_scope() message reworded. The old text led with
'v0.1 covers gov_types 0-3' which falsely implied the missing govids
were scope-excluded types when the more common real cause is a typo
or a guessed value. New message leads with typo + pre-2017 PID,
mentions scope exclusion as one possibility, and points at
cog_gov_search() as the recovery path.
Tests: 165 pass / 0 fail. check 0E/0W/0N.
