Create unified architecture for memo statistics, filters, and sorting
across all pages (Home, Explore, Archived, Profile) with proper
visibility filtering and consistent data flow.

Key changes:
- Rename HomeLayout → MainLayout to reflect broader usage
- Create useFilteredMemoStats hook for unified stats computation
- Create useMemoFilters/useMemoSorting hooks to eliminate duplication
- Refactor all pages to use unified hooks (~147 lines removed)
- Move Explore route under MainLayout (was sibling before)
- Fix masonry column calculation threshold (1024px → 688px+)

Architecture improvements:
- MainLayout computes filter/stats per route context
- Stats/tags based on same filter as memo list (consistency)
- Proper visibility filtering (PUBLIC/PROTECTED) on Explore
- MemoExplorer/StatisticsView accept stats as required props
- Eliminated optional fallbacks and redundant data fetching

Benefits:
- Single source of truth for stats computation
- Stats remain static (don't change with user filters)
- Reduced code duplication across 4 pages
- Better maintainability and type safety
- Proper security (no private memo leakage on Explore)

Fixed a bug where clicking checkboxes in task lists would toggle the wrong
checkbox when a memo contained multiple sections with separate task lists.

The issue was that TaskListItem was counting tasks only within the immediate
parent list (ul/ol), but the toggleTaskAtIndex function counts all tasks
globally across the entire memo. This caused index misalignment.

Changes:
- Add containerRef to MemoContentContext for proper task scoping
- Pass memoContentContainerRef through context in MemoContent component
- Update TaskListItem to count all tasks within the container scope

This ensures task indices are calculated consistently with the markdown
manipulation logic, fixing checkbox toggling in complex multi-section memos.

  * Removed separate FactorIcon component
  * Extracted handleRemoveFilter function
  * Improved imports organization

- Polished MemoFilters UI styles:
  * Changed to modern pill/badge design with rounded-full
  * Enhanced spacing and color schemes
  * Added smooth transitions and hover effects
  * Improved interactive remove button with destructive color hints
  * Better text readability with font-medium

- Added comprehensive filter support to all pages:
  * Explore page: Added full filter support (was missing)
  * Archived page: Enhanced from basic to full filter support
  * UserProfile page: Enhanced from basic to full filter support
  * All pages now support: content search, tag search, pinned, hasLink, hasTaskList, hasCode, and displayTime filters

- Consistency improvements:
  * All pages using PagedMemoList now have identical filter logic

Tag filters now support hierarchical matching where searching for a tag (e.g., "book") will match both the exact tag and any tags with that prefix (e.g., "book/fiction", "book/non-fiction"). This applies across all database backends (SQLite, MySQL, PostgreSQL) with corresponding test updates.

Remove disruptive error toasts when reverse geocoding or geolocation fails.
Instead, silently fall back to using coordinates as the location placeholder.
This improves UX for users in regions where OpenStreetMap is restricted

Fixed issue #5194 where changing the layout (List/Masonry) or sort direction
didn't update the UI until page refresh. The root cause was that ViewState
fields weren't marked as MobX observables, so the UI didn't react to changes
even though values were being persisted to localStorage.

Solution: Added constructor to ViewState that marks orderByTimeAsc and layout
fields as observable, following the same pattern used in other stores like
MemoFilterState.

Changed Cache-Control max-age from 7 days to 1 hour with immutable directive.
This prevents users from experiencing blank pages or JS errors when accessing
frequently redeployed instances (e.g., demo environments) where old cached
assets may reference files that no longer exist after redeployment.

Since Vite generates content-hashed filenames, the immutable directive prevents
unnecessary revalidation while the shorter cache duration ensures fresh assets
are served within an hour of redeployment.

chore: remove code-inspector-plugin from Vite configuration

- Deleted the `codeInspectorPlugin` from the Vite configuration in `vite.config.mts`.
- Simplified the plugins array to include only `react` and `tailwindcss`.

Fixes the root cause of non-reactive filtering. The MemoFilterState class
was not marking its fields as observable in MobX, so changes to the filters
array were not being tracked.

Added makeObservable configuration to mark:
- filters and shortcut as observable
- addFilter, removeFilter, removeFiltersByFactor, clearAllFilters, setShortcut as actions

This ensures that when tags are clicked and filters are added/removed,
MobX observer components will re-render and fetch new data.

Fixes filtering functionality that was broken due to improper use of
useMemo with MobX observables. The issue occurred because useMemo's
dependency array uses reference equality, but MobX observable arrays
are mutated in place (reference doesn't change when items are added/removed).

Changes:
- Remove useMemo from filter computation in Home, UserProfile, and Archived pages
- Calculate filters directly in render since components are already MobX observers
- Fix typo: memoFitler -> memoFilter in Archived.tsx

This ensures filters are recalculated whenever memoFilterStore.filters changes,
making tag clicks and other filter interactions work correctly.

Fixes a regression introduced in v0.25.2 where PostgreSQL IN clause
placeholders were not properly incremented, causing all parameters to
use the same placeholder index (e.g., $1, $1, $1 instead of $1, $2, $3).

This bug affected:
- ListReactions (ContentIDList) - caused "failed to list reactions" errors
- ListAttachments (MemoIDList)
- ListMemos (IDList and UIDList)

The fix combines placeholder generation and argument appending into a
single loop to ensure proper incrementing.
