Whole-program type checking in both modes

oxlint --type-aware --type-check now checks the whole program for each tsconfig selected by Oxlint's files,
in both default and fast (TSRS_FAST=1) modes (#930).

• Unselected, ignored and generated program files can report type errors. skipLibCheck still controls
  declaration checking; global diagnostics appear on the tsconfig. Oxlint ignores still control lint rules.
• Files sent by Oxlint that no discovered tsconfig includes are checked in an inferred program with tsgolint's
  fallback options, restoring their type errors in fast mode.
• Shared files report errors once: selected files use their mapped program; other files use the first selected
  configured program eligible to check them.
• Config discovery follows transitive project references, including custom-named configs, and preserves inherited
  compiler options (#934).

Selecting a clean file can now fail because another file in its program has a type error. Checking more files can
add work, especially with overlapping configs.

Other changes

• Speeds up cross-project references and initial auto-import completions in the language server (#936).
• Fixes memory growth across repeated full program rebuilds (#895).
• no-misused-promises avoids expensive type expansion for generic callbacks and overloads, and skips parameters
  without corresponding arguments (#907, #923).
• prefer-optional-chain reports optional-chain opportunities inside JSX callbacks (#910, #926).
• no-unnecessary-condition fixes false positives for unresolved conditional types such as Awaited<T>, while
  retaining reports when constraints prove a condition always truthy or never nullish (#911).
• no-unsafe-assignment fixes false positives for quoted, numeric and computed object properties contextually
  typed as unknown, and reports any assignments to JSX props (#914, #924).
• prefer-includes handles escaped backslashes in regex patterns and preserves escaping in .includes() fixes (#918).
• no-unnecessary-type-assertion reports assertions that may supply a generic call's inferred type arguments,
  recommending explicit type arguments without an automatic removal fix (#925).

Packages remain available for macOS arm64/x64, Linux x64/arm64 (glibc and musl), and Windows x64. Windows ARM64
(#903) awaits npm setup and a passing native PGO release dry run.
