Fixes the scan-scope half of CLI-1ES (scandir errors, ~20k events).

The findProjectRoot spans on the failing events show the CLI isn't failing inside projects. It's walking roots that aren't projects at all:

• $HOME with reason: language: a stray ~/package.json makes $HOME the project root, including for runs that start in a marker-less subdir like ~/.agent/workspaces/<id>. The fix(cli): Send native detector datasets and conditions for metric alerts #1591 guard only checks reason === "fallback", so these runs still walk ~/Library/CloudStorage, ~/OrbStack, OneDrive FUSE mounts, and ~/Documents/*.trace. That's where the ETIMEDOUT / EIO / errno -11 / ECANCELED events come from. It can also pick up an unrelated DSN from anywhere under $HOME.
• /tmp with reason: fallback: this walks other processes' FUSE mounts (AppImage /tmp/.mount_*, FreeRDP clipboard dirs), which fail with ENOTCONN.

shouldSkipDownwardScan() now skips the file scan whenever the root is $HOME, an ancestor of $HOME, or a shared temp root, no matter which marker picked it. SENTRY_DSN still works. A project with a marker inside /tmp still gets scanned.

Before: detectAllDsns() with ~/package.json and a leftover ~/notes/old-demo.ts, run from ~ or ~/.agent/ws1:

{
  "projectRoot": "~",
  "reason": "language",
  "detected": ["https://abc@o1.ingest.sentry.io/1  (notes/old-demo.ts)"]
}

After: same setup, sentry issue list --verbose:

[debug] [resolve-target] No config defaults set, trying DSN auto-detection
[debug] [dsn] Skipping DSN file scan: project root ~ (language) is the home directory, an ancestor of it, or a shared temp directory
[debug] [resolve-target] No DSNs found in source code or env files, trying directory name inference

{ "projectRoot": "~", "reason": "language", "detected": [] }

Tradeoff: a marker-less directory under a $HOME that has a marker no longer gets scanned. Before this change it scanned all of $HOME. SENTRY_DSN, .sentryclirc, or a project marker in that directory covers it.
