tasks: add "every N weeks/months/days/years" recurrence (KC-70)

Recurrence previously only supported 5 fixed rules with no interval.
Adds TaskItem.recurrenceInterval (optional, nil = 1, so every existing
task is unaffected), a stepper in the shared create/edit sheet, quick-add
NLP for phrases like "every 2 weeks"/"biweekly"/"fortnightly", and
threads the interval through both countdown widgets so their progress
bars size correctly for biweekly/etc tasks too.

Built on KC-69's consolidated RecurrenceRule engine. Verified two things
by actually compiling and running standalone swiftc drivers rather than
just reading: the core interval math (44/44, unchanged from KC-69) and
the new quick-add regex patterns against realistic phrases including
"look into tru housing options every two weeks" (11/11 passing).

+## KC-70 — "Every N weeks/months/days/years" recurrence
+
+Status: Implemented (not build-verified — no iOS runtime here, but the core
+recurrence math and the quick-add regex are both real, executed-and-passing
+standalone verification — see Note)
+Reported by: User — "Look into TRU housing options every two weeks," and
+generalized to "every 1 week or 2 or 3," "every 2 months," etc.
+Area: Task model, task editor (Matrix + quick-add), quick-add NLP, both
+countdown widgets
+
+### Description
+Recurrence previously only supported 5 fixed rules (Daily/Weekly/Monthly/
+Yearly/Every Weekday) with no interval — "every 2 weeks" or "every 3
+months" had no representation. Built on top of KC-69's consolidated
+`RecurrenceRule` engine (which already accepted an `interval` parameter in
+anticipation of this).
+
+### Change
+- `TaskItem.recurrenceInterval: Int? = nil` — optional, same safe-decode
+  pattern as every other recurrence field; nil means 1 everywhere, so
+  every existing task is unaffected.
+- `TaskItem.recurrenceDisplayLabel` — "Weekly" stays "Weekly" at interval
+  1, becomes "Every 2 Weeks" etc. above that. Delegates to a new
+  `RecurrenceRule.displayLabel(label:interval:)` (Shared/) rather than a
+  4th hand-written copy of this formatting.
+- `TaskDatePickerSheet` (the shared create/edit sheet used by both Matrix's
+  task editor and quick-add): new "Every N" `Stepper` row (1...30),
+  visible whenever a repeat unit other than "Every Weekday" is selected.
+  `repeatDisplayValue` switches to the "Every N X" format once N > 1.
+- `addTask`/`updateTask` (`TaskItem.swift`) and both `TaskDatePickerSheet`
+  call sites (`MatrixView.swift`, `TodayView.swift`) thread the new field
+  through.
+- Quick-add NLP (`NLTaskParser.parseRecurrence`): new
+  `parseIntervalRecurrence` recognizes "every 2 weeks," "every three
+  months," "biweekly," "fortnightly," "bimonthly" (checked before the
+  existing plain-unit patterns, which stay untouched). "every 1 X" falls
+  through unrecognized — matches how "every week" behaves today, not a
+  regression.
+- Widgets: `WidgetTask`/`RawTask` (`WidgetData.swift`) and `EventEntity`
+  (`EventCountdownWidget.swift`) gained `recurrenceInterval`, threaded
+  through both countdown widgets' span calculations (`KisaniCalWidgets
+  .swift`'s `recurrenceSpan(for:)`, `EventCountdownWidget.swift`'s
+  `resolveSpan`/`recurrenceSpan`) so a biweekly task's countdown bar sizes
+  correctly in both widget families, not just the main app's Calendar/
+  Matrix/Today views.
+
+Files: `KisaniCal/Models/TaskItem.swift`, `KisaniCal/Views/TodayView.swift`,
+`KisaniCal/Views/MatrixView.swift`, `Shared/RecurrenceRule.swift`,
+`KisaniCalWidgets/WidgetData.swift`, `KisaniCalWidgets/KisaniCalWidgets.swift`,
+`KisaniCalWidgets/EventCountdownWidget.swift`.
+
+### Note
+Not build-verified in Xcode (no iOS runtime here). Two things WERE
+actually verified by compiling and running standalone `swiftc` drivers
+against the real logic (not copies, not just read):
+1. `RecurrenceRule` itself — 44/44 cases (see KC-69), unchanged by this
+   commit.
+2. The new quick-add regex patterns — extracted into a standalone driver
+   and run against realistic phrases including the user's own example
+   ("look into tru housing options every two weeks" → Weekly/2) plus
+   biweekly/fortnightly/bimonthly and negative cases (plain "every week"
+   correctly does NOT trigger the interval path) — 11/11 passing.
+The SwiftUI layer itself (the Stepper row, bindings, sheet wiring) is
+self-reviewed only — balanced braces/parens confirmed per-file, one
+pre-existing stray `(` in `TaskItem.swift` predates this (see KC-62).
