chore: mark v0.1.18

[Yury Semikhatsky (yury-s)]

#443 was merged into its stacked base branch instead of main, so the version bump never landed on main. Re-landing it.

Highlights

• install --skills supports the -g flag (microsoft/playwright#42087) — installs the skill into your home directory instead of the current workspace. (microsoft/playwright#42099)
• Generated code in Python, Java and C# (microsoft/playwright-mcp#1696) — code can be generated in Python, Java and C# in addition to JavaScript. (microsoft/playwright#42106)
• Configurable post-action settle delay — tune how long the CLI waits for the page to settle after each action. (microsoft/playwright#41924)

Fixes

• feat(mcp): emit structured snapshot in --json responses — --json no longer wraps formatted text in a string; responses carry a structured page snapshot. (microsoft/playwright#42076, microsoft/playwright#42098)
• feat(mcp): add snapshot.boxes config to include bounding boxes in snapshots — bounding boxes can now be enabled globally via config rather than per snapshot. (microsoft/playwright-mcp#1695, microsoft/playwright#42102)
• fix(cli): exit with non-zero code when the tool result is an error — failed commands no longer exit with status 0, so scripts and agents can detect errors. (microsoft/playwright#42028, microsoft/playwright#42042)
• fix(cli): accept multiple files in upload command — upload no longer rejects a second file although it advertises "one or multiple files". (microsoft/playwright#42047, microsoft/playwright#42057)
• fix(mcp): reconnect to the browser after disconnect — the relay reconnects after the browser extension disconnects. (microsoft/playwright#41874, microsoft/playwright#41966)
• fix(mcp): launch the Chrome profile that has the extension installed — attach no longer targets a different profile than the one with the extension. (microsoft/playwright#41916, microsoft/playwright#41939)
• fix(mcp): pass noDefaults for extension CDP connections — extension connections no longer override existing browser defaults. (microsoft/playwright#42117, microsoft/playwright#42119)
• fix(mcp): clear dialog modal state when dialog is closed out of band — dialogs dismissed by hand in headed mode no longer leave the session stuck in a modal state. (microsoft/playwright#42032)
• fix(mcp): report malformed JSON config instead of falling back to INI — a broken JSON config file now produces a clear error instead of being silently parsed as INI. (microsoft/playwright#41909)
• fix(mcp): surface the missing executable path when a browser isn't installed — clearer error message pointing at the missing browser executable. (microsoft/playwright#41941)
• fix(mcp): identify downloads explicitly — downloads are labeled explicitly in command responses. (microsoft/playwright#41933)
• fix(mcp): validate Host and Origin on CDP relay WebSocket upgrades — hardens the extension relay against unauthorized cross-origin connections. (microsoft/playwright#42103)
• fix(mcp): escape user input in codegen output — special characters in your input are escaped correctly in the generated code. (microsoft/playwright#41962)
• fix(mcp): mention PLAYWRIGHT_MCP_EXECUTABLE_PATH in extension not found error — points at the escape hatch when the extension browser can't be located (e.g. on WSL2). (microsoft/playwright#42092, microsoft/playwright#42122)
• perf(mcp): skip aria snapshot capture when the response discards it — commands that don't need a snapshot run faster. (microsoft/playwright#41923)
• The v0.1.17 fix for goto crashing on privileged pages (chrome://…) was reverted upstream: the crash originates in the browser process itself, and the fix only masked it. (microsoft/playwright#41931)
