Improve heap profile memory usage by lazily loading js objects
* Read V8 map data directly, for signal safety * Allow passing in an ACF key object externally to the profiler. * time-profiler.ts uses it to pass an AsyncLocalStorage (ALS) as the key.
#281) use MapAllocationProfile by default to get heap profiler

When lineNumbers is enabled, the column is always zero. If only one occurence of a call occurs on one line then that is correctly selected. However, in cases where the same function is called multiple times in the same line it will be unable to differentiate them and would use the unmapped value. This now makes it select the first call in the line as a best-guess for the match, and in Node.js v25 will use the new column field in LineTick to select the correct column where possible.

#292) * Rewrite SourceMapper to use eager directory scan with sourceMappingURL support Replace `SourceMapper.create(searchDirs[])` with a two-part API: - `new SourceMapper()` constructs an empty mapper synchronously - `await sm.loadDirectory(dir)` populates it asynchronously - SourceMapper.create() is kept as backwards-compatible delegate This separates construction from loading, allowing callers to fire off the async scan without blocking profiler initialization. In production the scan is fire-and-forget (completes well before the first profile is taken); in tests it is awaited directly. The directory scan now uses a two-phase approach per JS file: Phase 1 (higher priority): reads each .js/.cjs/.mjs file and checks for a `sourceMappingURL` annotation (per TC39 ECMA-426). Inline `data:application/json;base64,` URLs are decoded in-memory; external file URLs are loaded from disk if the file exists. The implementation first attempts to read only a 4k tail of the file, and if it is not sufficient falls back to reading the entire file. Phase 2 (fallback): processes .map files found in the directory using the original logic (file property → naming convention). Skips any JS file that Phase 1 already resolved. processSourceMap is refactored to parse just the `file` JSON property before creating the SourceMapConsumer, so we can bail out early (skipping consumer creation) if the JS file was already loaded in Phase 1.

feat: track declared-but-missing source maps and report them in profile comments When a JS file has a sourceMappingURL annotation but no map file is found after both phases of directory scanning, SourceMapper tracks it as declared-missing. mappingInfo() for such files returns a SourceLocation with missingMapFile: true, and serialize() emits a single dd:has-missing-map-files token into profile.comment when at least one such file is encountered. Inline data: URL annotations in all valid forms (including data:application/json;charset=utf-8;base64,...) are correctly handled and never produce false missing-map signals.

Note: #300 is in the list of applied commits, but since it was faulty it failed the release and it was removed from it by editing the release branch. It will be re-added in the next release together with a fix for the problem. Since it only addresses upcoming Datadog tagging protections, it is not material to the release.
