Stabilize Components 3 consumer contracts

[woksin]

Summary

Delivers the source-compatible Components stabilization work without changing the package's UI foundation. This release remains backed by PrimeReact 11, rendering consumers must continue to install its peers, and PrimeUI licensing still applies—including when Components is used as a wrapper. The renderer-independent React Aria architecture will be delivered separately as an explicitly documented and reviewed major release.

The reported DataPage default-filter failure is covered by regression and browser evidence but was not reproducible on the current implementation. clientFiltering remains accepted as a deprecated no-op: filtering is page-local and server totals remain authoritative.

Added

• Published and regression-tested the Components 3 / PrimeReact 11 pass-through compatibility contract (Components has no stable pass-through slot contract for unstyled rendering #122)
• Added direct DatePickerInput identity, disabled, read-only, and button-bar controls (DatePickerInput does not expose disabled, readOnly, id, or showButtonBar #154)
• Added localizable column-filter labels and custom filter elements (The column filter overlay is unlocalizable and Column has no filterElement seam #155)
• Added Cratis-owned filter match modes and source-compatible custom matcher registration (DataTableFilterMeta is Cratis-owned but PrimeReact-valued: the match-mode vocabulary and matcher registration are PrimeReact's #164)
• Added a substitutable, cross-copy-safe toast dispatch contract (toast is re-exported verbatim from primereact/toaster, so the entire notification surface is unsubstitutable #165)
• Added packed-consumer CI coverage for Arc 20, 21, and 22

Changed

• Expanded the supported Arc peer range through Arc 22 (Components 3.4.0 peer ranges reject Arc 22 #166)
• Documented complete-result filtering as a server-side query responsibility (clientFiltering is declared on DataTableForQuery, DataTableForObservableQuery and DataPage, forwarded by DataPage, and never read by any implementation #159)

Fixed

• Added regression and browser coverage for DataPage default filters without reproducing the reported empty-table failure (DataPage renders an empty table when given defaultFilters (any value, including {}) #149)
• Aligned DatePickerInput pass-through typing with the live input slot (DatePickerInput's pt type declares a pcInputText slot the runtime never emits, so the attributes are dropped and tsc stays green #150)
• Prevented DatePickerInput validation state from leaking to the DOM (DatePickerInput forwards invalid to the DOM, so React rejects it as a non-boolean attribute #151)
• Routed Dropdown identity and accessibility props to the focusable combobox (Dropdown names the wrapper, not the focusable combobox, so every dropdown has no accessible name #152)
• Kept Dropdown trigger and filter placeholders independent (Dropdown overrides pt.filter.placeholder with the trigger's placeholder #153)
• Preserved dismiss controls for custom toast bodies and exposed toaster pass-through configuration (A custom toast render silently removes the toast's dismiss control, and Toaster exposes no pt #156)
• Derived paginator accessibility labels from the active locale (TablePaginator's ARIA labels default to English rather than the configured locale #157)
• Hid decorative dialog footer icons from accessibility APIs (Dialog footer buttons include the decorative PrimeIcon glyph in their accessible name #158)
• Suppressed query empty states until the first result is available (The query-driven data tables render emptyMessage before the first result arrives, and expose no seam for the pending state Arc already gives them #160)

Deprecated

• Retained clientFiltering for source compatibility while making its page-local behavior explicit (clientFiltering is declared on DataTableForQuery, DataTableForObservableQuery and DataPage, forwarded by DataPage, and never read by any implementation #159)
