Timers, upgrades, and bug fixes land across Deno

Multiple user-facing fixes: web timers were rebuilt on core timers, delta upgrades compressed patches, and several runtime/type bugs were patched.

Web timers now run directly on core timers (bartlomieju860acab)

setTimeout/setInterval in ext/web no longer go through Node's Timeout class; they’re built straight on core.createTimer. This also adds explicit AsyncContext save/restore around callbacks and keeps the numeric timer-ID mapping in ext/web.

Delta upgrades now ship compressed bsdiff patches (bartlomieju5d41c46)

The upgrade path now zstd-compresses generated .bsdiff artifacts before upload, dramatically shrinking the patch size. The client detects both the new zstd-wrapped format and older raw patches so existing published deltas continue to work.

Lazy-loaded ESM now survives concurrent imports (bartlomieju96aeaf2)

A race in concurrent dynamic imports could drop shared lazy-loaded module sources and fall through to an unsupported loader.load() path. The fix keeps lazy ESM source available across loads and adds regression coverage for the concurrent import case.

Transpilation preserves JSDoc newlines after block comments (bartlomiejua865b21)

deno transpile now post-processes SWC output to restore newlines after multi-line block comments, avoiding collapsed JSDoc like */ export function .... The pass is skipped when source maps are requested so generated mappings stay correct.

--config path resolution no longer panics on URL conversion failures (bartlomieju31969b4)

Workspace discovery now propagates URL conversion errors instead of unwrapping them, fixing a crash when a config path or its parent can’t be turned into a file:// URL on the host platform. Users get an error instead of a panic.

Brotli restored in DOM and webworker compression types (bartlomiejue4c2fff)

The vendored TypeScript lib patches were restored so CompressionFormat again includes "brotli" in lib.dom.d.ts and lib.webworker.d.ts. This keeps CompressionStream("brotli") type-checking correctly after TS upgrades.

Node fs.promises wrappers drop stray extra arguments (bartlomieju728239f)

Promise wrappers for callback-style fs methods now truncate surplus positional args before calling through, fixing cases like paths.map(fs.promises.unlink) that previously passed index/array into the underlying callback signature. This removes a real footgun in Node-compat code.

Node base64Slice now accepts omitted args (turtletongue5bd5a3b)

base64Slice was tightened to allow missing arguments, aligning the polyfill with expected Node behavior.

Other misc changes
