Sync Linux Computer Use → agent-sh/computer-use-linux

[github-actions]

A merge to main touched computer-use-linux/** (the vendored Linux Computer Use crate).

Propagate the change to agent-sh/computer-use-linux if it is not codex-specific glue.
Keep the upstream generic naming there — do not push codex-* /
CODEX_COMPUTER_USE_* names, identity.rs, or the chrome-extension host upstream.

• Compare: 26db707...781201d
• Triggering commit: 781201d

Once synced, bump both crates to the same enumeration. A version mismatch
between this crate and the standalone one means a sync is still pending.

I completed the bounded audit for this reminder.

Immutable inputs:

• downstream range: 26db70741861f407820370585f22796396e32f83..781201d7907efc28ef3c20e7a328b6269b746d34
• current protected chatgpt-linux main: 4762b207ce71c5fda2ba547ab6987b601990d8b7
• current vendored computer-use-linux tree: 0f122b7cdeb26bf13faacaf8b16445ee18a7d62e
• standalone baseline: 663930fef8d1bee64b7b8f833b68cff3196059e3
• reviewed standalone export: bebbdcc41df3dac1cacb79ad3bca3c48072c06eb in agent-sh/computer-use-linux#96

Disposition of every meaningful delta in this range:

• Already present: schema-only received suppression (ec9e1f42); the absolute-pointer backend and probe (789b02ce, 0891ab70); screenshot/crop behavior (21906d03); structured capability/preferred-backend maps (ca9eda57); MCP safety annotations (b1e8ca2f, 27d25438); blocking-uinput isolation (146b9c37); and negative-origin crop behavior from a1f5bb03.
• Exported generically: the a1f5bb03 last-pixel axis maxima/clamp, unsupported-button fallthrough, and complete AT-SPI capability gating. The standalone regressions cover exclusive-edge coordinates, extended buttons reaching the existing fallback, an unreachable AT-SPI bus, and a false toolkit status. Button validation now occurs before absolute-device setup.
• Superseded: numeric version commits 4a8b6e25 and 0f5cbc89; merge/trigger carriers 4e08af28 and 781201d7. The standalone project retains its own 0.4.9 version contract.
• Not exported: no ChatGPT/Codex identity, app authority, browser-host, environment, or package contract occurs in the standalone delta.

I am closing this source-range reminder because its audit and export are complete. #159 retains the upstream PR disposition and final closeout record.
