Switching between the shared browser and this machine's own previously meant
leaving pi and relaunching with BU_CDP_HTTP — and, less obviously, killing the
daemon first, or the switch silently did not happen.

  /browser-target                 show the current target
  /browser-target local           this machine's browser
  /browser-target default         the built-in default
  /browser-target host:port       somewhere else

Precedence becomes env &gt; stored &gt; default. The environment still wins so a
one-off `BU_CDP_HTTP=… pi` is never silently overridden by a choice made days
ago; when it is set, the command says so rather than pretending to obey.
Clearing falls back to the default rather than to local — "use the usual
browser", not "go local".

The daemon is the reason this needed more than a settings write. It is
machine-wide, resolves its target once per process, and holds the WebSocket to
the old browser, so re-reading the store would leave tool calls going to the
old browser while /browser-status reported the new one. The command therefore
replaces the process: the daemon now honours an inbound control/shutdown (the
action already existed in the protocol, previously only sent daemon→client),
and stopDaemon() asks for it and polls until the process is really gone before
ensureDaemon() respawns it against the new target. /browser-status now reads
the store too, so it cannot disagree with what the tools will do.

Persistence mirrors the profile pin: atomic temp-file-plus-rename, and every
read failure degrades to "nothing stored" so a corrupt file falls back to the
default instead of breaking browser control. It is a separate file from the
pin, so damage to one cannot cost you the other. The stored value stays in
BU_CDP_HTTP's vocabulary so there is exactly one resolution path.

62 tests: the full precedence table including the stored tier, that a bad value
is blamed on the source that set it rather than sending you hunting through
shell config, that the command only accepts values resolution can actually use,
and eight ways of damaging the store file.

Drops leading blank lines where a file header was removed, collapses
double blank lines, and closes the empty catch/handler blocks whose only
content had been a comment. Whitespace only.

Removes module banners and comments restating the code. Keeps one-line
notes for the ProcessSingleton user-data-dir rule, the sentinel-URL and
async-spawn-error quirks, the replicated getAgentDir, pi's tilde-expansion
mirroring, the Windows wmic removal, the macOS/Linux process-identification
quirks, the picker's undefined-means-cancel contract, and the deliberately
unpersisted browserContextId.

* feat: pin the agent to a chosen browser profile (#15)

Harness tabs were created with a bare Target.createTarget, which places
them in Chrome's defaultBrowserContextId — and that value follows window
focus. Which profile the agent acted as therefore depended on which
browser window the user last clicked, so the same task could run as a
work account on one run and a personal account on the next.

/browser-profile lists the connected browser's profiles as "Name (email)"
and pins one to ~/.pi/agent/browser-harness.json, so the choice outlives
the session. The same picker appears on first browser_setup when nothing
is pinned; with no interactive UI, or on cancel, setup continues with a
note and the previous behavior.

Chrome offers no direct route to another profile: Target.createTarget
rejects a foreign browserContextId, and openerId does not inherit the
opener's context. The window is opened through the browser's own command
line (--profile-directory, handed to the running browser by Chromium's
ProcessSingleton) and identified by a unique file:// sentinel page, since
a bare about:blank#token argument is discarded. Further tabs come from
window.open evaluated with userGesture: true — the only CDP-reachable way
to place a tab in a non-default browser context — correlated by a unique
token so concurrent isolated tabs stay distinct. A failed handshake is
reported, never silently redirected to another profile.

All four tab-creation sites now funnel through cdp/target-factory, so
open_urls and the isolated tabs behind web_search / read_page cannot run
with a different profile's cookies than the visible tabs.

Also fixed along the way: snap Chromium is discovered, Windows uses
%LOCALAPPDATA%, browsers launched with an explicit --user-data-dir are
found, the running browser is chosen by ranking candidates against the
connected user-data-dir rather than taking the first process found, and
an installed-but-closed browser no longer reads as running.

CI runs the profile suites and a real-browser end-to-end test on ubuntu,
macOS, and Windows — profile discovery is the one part of the harness
whose behavior genuinely differs per OS.

* fix: single-flight harness window creation

Isolated tabs run concurrently (browser_read_page is registered
unserialized), so several could each find "no harness window" and create
one — two blank windows before this feature, two LAUNCHED profile windows
after it. ensureHarnessWindow now shares one in-flight creation per
client.

Sharing introduces a second hazard: freshlyCreated is a claim on the seed
tab, and if every waiter received it, they would all drive the same tab.
Only the caller that started the creation keeps the claim; the rest open
their own tab beside it.

Covered by test/manual/profile-concurrency-test.ts (five concurrent
isolated tabs, pinned and unpinned: distinct targets, one window, correct
profile), wired into CI on Linux only — the coordination is pure JS and
identical across platforms.

* fix: tilde expansion differs by purpose on Windows

CI on windows-latest caught this: join("~", "x") yields "~\x" there, and
expandTilde only handled "~/".

The two uses are not the same, so they no longer share a helper. The
agent dir stays byte-compatible with pi's own expandTildePath ("~/" only,
every platform) — being more lenient would put the pin file somewhere pi
never looks. $CHROME_USER_DATA_DIR is ours to interpret, so it accepts
"~\" as well, which is what a Windows user would type.
