Changes since last release

Forward-looking audit fixes (patches + CI hardening, verified against v1.13576.4)

A full audit of patches/docs/CI against the current bundle found the suite healthy (51/51 apply, Cowork contract intact in both native and KVM modes, no new Linux gaps). Four items were worth fixing, all low-risk:

• fix_quick_entry_ready_wayland: fixed a latent runtime bug. The replacement hardcoded a logger (R.error) that does not exist at the patched call site (the live logger is S); the patch applied cleanly and passed node --check, but a rejected ready-to-show promise would throw a ReferenceError in the very catch meant to swallow it. Now captures and reuses the upstream logger var + catch param so it survives re-minifies.
• fix_imagine_linux: retargeted Patch C to the renamed flag. The Visualize/Imagine CCD gate 2204227020 was renamed to 3516166472 upstream, so Patch C had silently become a no-op (its standalone uses, including the read_widget_context tool registration, were no longer forced ON). Retargeted to the new ID. Also rewrote the Patch B/C idempotency checks to assert the patched end-state and fail loudly if the flag disappears, instead of treating flag-absence as success.
• fix_native_frame_renderer: converted to a regression guard. Upstream upstreamed the fix (the main-window title-bar component now returns null natively), so the patch had been silently no-opping via an accidental guard. It now positively asserts the upstream null short-circuit and fails the build if a future release reintroduces the pointer-absorbing drag region.
• CI: glibc floors are now enforced, not just logged. The node-pty rebuild asserts the GLIBC_2.31 floor (Debian 11 / Ubuntu 22.04) and fails loudly instead of silently shipping an un-rebuilt binary when version detection fails; the aarch64 kwin-portal-bridge gained the same objdump-based GLIBC_2.39 gate the x86_64 binary already had.

Docs: added the missing fix_open_in_editor_linux row to the README patch table and corrected the obsolete fix_native_frame_renderer row; noted the 2204227020 -> 3516166472 rename and fixed contradictory version headers in CLAUDE_FEATURE_FLAGS.md. CLAUDE.md gained a strictness rule forbidding false-success reporting - an "already patched" line must assert the patched end-state, never the mere absence of the pre-patch pattern.

Upstream (v1.13576.4) - build bump, no patch work

• Version bump v1.13576.1 -> v1.13576.4 (patch-level rebuild of build 13576, hash 414f858c). Re-minify only; bundle functionally identical.
• All 52 patches apply unchanged. Package built cleanly; node --check passes. The lone validator "FAIL" (fix_ion_dist_linux) is a manual-extract artifact - ion-dist lives in the MSIX resources, not app.asar; the patch applies fine against the extracted SPA.
• No semantic changes vs v1.13576.1: platform-conditional counts (linux 10, darwin 77, win32 +1 vendored path helper), Agent SDK copies (0.3.174 / 0.3.177), built-in MCP servers (1), and all fragile anchors are unchanged - the diff is pure minified-identifier churn.
• No baseline-doc changes. Bumped .upstream-version -> 1.13576.4.

Built-in terminal fixed (re: #143)

• New fix_terminal_shell_linux.nim (51 patches total): the built-in agent/Cowork terminal now spawns a Linux shell instead of PowerShell. Upstream hardcodes the node-pty shell to powershell.exe on every platform, so on Linux execvp(3) fails and the PTY dies instantly ("Shell exited." / exit code 1). The patch rewrites only the shell string into a platform-aware ternary, anchored on the sole shell:"powershell.exe" occurrence. Thanks to Yannick Schäfer (@boommasterxd) for the fix (#144).
• Off-Windows shell selection falls back $SHELL → /bin/bash → /bin/sh. The /bin/sh tier was added on top of the PR for NixOS (Nix flake target), which ships no /bin/bash by default; a runtime require("fs").existsSync check keeps the PTY from going dead when $SHELL is unset.
