chore(release): 0.27.0-fork.50 — tab-title truncation + multi-agent/eval/type docs

From Hermes's fork.49 re-dogfood (9/11 fixes confirmed PASS):
- tab list: a page can set its title to a multi-KB string (= a giant URL); cap
  the title column like the URL so the row stays readable.
- skill: clarify that true multi-agent isolation needs the extension-connect path
  (per-session tab groups) — raw `--cdp` shares the browser, so a sibling
  session's `open` can navigate your tab. Use the extension for concurrent agents.
- skill: prefer `eval --json` for array/object results (plain render is
  multi-line / pipe-hostile); note type/fill don't fire keydown (use `keyboard
  type` when key events are required).

(Hermes's "find-text click bypasses humanize" was a false alarm — verified both
paths curve; the apparent 1-vs-12 was cursor continuity on the same target.)

 `0% stealth` on CreepJS is the key number: because the connect path patches **nothing**, there is no override for a lie-detector to catch.

+When using `--launch` mode (standalone browser), a full suite of stealth patches is applied instead, and it passes the suite above — with one caveat: CreepJS reports **~20% stealth** because the srcdoc-iframe `contentWindow` patch trips its `hasIframeProxy` probe (the proxy that hides automation is itself a tell). Everything else is clean (`0% headless`, sannysoft/browserscan green, Cloudflare passed). Set **`AGENT_BROWSER_DISABLE_IFRAME_PROXY=1`** to drop that patch for a clean **0% stealth** (trades the niche srcdoc-iframe masking). The **extension-connect path** (your real Chrome) injects zero JS and is unaffected — it's the genuine 0% path.

+Prefer `eval --stdin` (heredoc), `eval --file <path>`, or `eval -b <base64>`

+large scripts — inline `agent-browser eval "..."` is shell-mangled and works
+only for simple ASCII expressions.
+
+**`eval` runs in the page's MAIN world and state persists across calls**, so a
+top-level `const x`/`let x`/`var x` in one call collides with the next
+(`SyntaxError: Identifier 'x' has already been declared`). Either use unique
+names, assign to `window.x`, or wrap the body in an IIFE
+(`(() => { const x = …; return x; })()`).
+
+**For array/object results, use `eval --json`** — the plain renderer
+pretty-prints across multiple lines, which `tail`/`head`/pipes mangle; `--json`
+emits one parseable line. Also note **`type`/`fill` insert text without firing
+`keydown`/`keyup`** (CDP insertText) — the value lands, but a page that gates on
+key events (some search-as-you-type widgets) won't react; use `keyboard type` (or
+`press` per key) when real keystrokes are required.
