* Add multi-day calendar selection with custom popover UI
Replace native DatePicker with a custom-themed CalendarPopover supporting
non-contiguous multi-day selection. Add --days CLI flag for comma-separated
date filtering that post-filters from the bounding range scan.
CLI: parseDaysFlag() parses and validates dates, filterProjectsByDays()
filters turns to only selected days. Verified that sum of individual --day
calls matches --days output across cost, calls, activities, models, and
providers.
Swift: DataClient passes --days for multi-day, with single-day fallback.
AppStore tracks selectedDays as Set<String> with PayloadCacheKey support.
CalendarPopover uses pending state committed only on Done tap.
* Clear + Done in calendar resets to current period
When user clears all selected days and taps Done, switch back to the
active period instead of silently keeping the old day selection.
* Expose per-day one-shot data in daily JSON output
Closes#279.
Adds turns, editTurns, oneShotTurns, oneShotRate to each entry of the
`daily[]` array in `codeburn report --format json` output. The data was
already computed internally for activity-level rollups; this just buckets
it by date so consumers building daily-resolution efficiency dashboards
(streak tracking, heatmaps, rolling-window charts) don't have to re-derive
the rate from period-level activities.
Counting matches parser.ts categoryBreakdown semantics:
- every turn counts toward `turns`
- turns with hasEdits=true count toward `editTurns`
- edit turns with retries=0 count toward `oneShotTurns`
- oneShotRate is null (not 0) when editTurns=0 — a chat-only day's rate
is undefined, and reading it as 0% would be misleading
Real consumer named in the issue: a 10-developer internal usage tracker
that scores days by cache hit + cost/call + (now) one-shot rate.
* Strengthen daily/activities reconciliation + CHANGELOG entry
- Fall back to turn.assistantCalls[0]?.timestamp when turn.timestamp is
missing so daily aggregate doesn't drop turns that activities[] keeps.
Previously sum(daily[].editTurns) could be < sum(activities[].editTurns)
for sessions starting with assistant entries before any user line.
- Add Unreleased CHANGELOG entry for the daily one-shot fields.
