* fix(browser)!: keep the Chromium sandbox for REA-launched browsers
Playwright appends --no-sandbox unless a launch passes
chromiumSandbox: true. Neither the browser scenario launch nor the native
module resolver passed it, so every REA-launched Chromium ran without its
sandbox and REA_BROWSER_NO_SANDBOX had no effect.
Both launch sites now take the sandbox decision from ChromiumSandbox.ts:
off on Android or when REA_BROWSER_NO_SANDBOX=true, on otherwise. When
Chromium reports that it cannot start its sandbox, the launch failure's
remediation names the opt-out.
Fixes#8722
BREAKING CHANGE: hosts where Chromium cannot create its sandbox, such as
root users and Linux containers without user namespaces or a setuid
sandbox, now fail to launch until REA_BROWSER_NO_SANDBOX=true is set.
* fix(browser): name the sandbox opt-out on any sandboxed launch failure
Chromium reports an unusable sandbox through several unrelated startup
messages, including a misconfigured setuid helper and a refused namespace
move, and Playwright recognizes only some of them. Matching individual
messages missed real failures, so a sandboxed launch failure now always
names REA_BROWSER_NO_SANDBOX=true as a conditional remediation and the
retained startup diagnostics show whether the sandbox was the cause.
* fix(browser): keep default recovery for resolver failures after launch
The module resolver's outer catch also covers context, navigation and
evaluation failures after the browser launched. Attaching the sandbox
remediation there replaced their default recovery guidance. Attach the
shared launch remediation only when a sandboxed launch itself fails.
* docs(browser): note the Android sandbox exception for module traces
* fix(web): omit importer integrity for the trusted resolver stub
Import-map integrity that covers the selected importer was applied to REA's
replacement resolver script. Strip only those integrity entries from the
installed map so native resolution can proceed while preserving dependency
integrity and the caller-selected map identity.
Fixes#8544
* fix(web): keep __proto__ import-map integrity keys on a null prototype
Serialize resolution with shutdown, retain the owned browser after close failures, and retry cleanup before another launch. Wire cleanup through the shared service and CLI/MCP lifecycles, preserving primary failures and completed native reports alongside cleanup diagnostics.
Separate the browser resolution workflow from lifecycle ownership. Validation: seven resolver source tests, eleven application tests, MCP shutdown retry, public CLI parity, and full static/architecture checks passed. Real Chromium behavior remains unverified.
* feat(browser): trace captured website module imports
Compose verified exported scripts, inert native import syntax and a narrow
Chromium resolution port. Preserve query/fragment identity, import-map context,
all reported capture candidates and explicit unknown execution. Share named
CLI/MCP contracts and retain native reports, diagnostics and cleanup failures.
Add focused boundary regressions and a real module-loading oracle to the
existing conditional Chrome lane. No captured application code is executed
by module tracing, and no selected website asset is refetched.

* fix(browser): preserve module contexts and source bindings
Keep capture completeness inline, validate actual source text against its
digest, and separate unsupported URL contexts from malformed input.
Use the importer origin for native module resolution and the selected map
base independently, including mixed HTTP/HTTPS and escaped HTML attributes.
