Summary

Fixed: omnyshell ide segfault on first frame

• In compiled binaries, omnyshell ide . crashed with SIGSEGV (si_addr=0xf in ScreenBuffer.renderDiff). Seen on Linux x64 (Dart 3.13.0) and reproduced on macOS arm64.
• Cause: a Dart VM AOT bug, [vm] Probably LICM bug dart-lang/sdk#63413. LICM hoists previous._cells above the reusable guard that promoted previous to non-null. It affects 3.11.0–3.13.7 and is fixed in 3.14 beta and 3.15 dev. I filed a stable backport request: Request: cherry-pick LICM fix 8b8021bc (#63413) to stable 3.13 — AOT SIGSEGV still reproduces on 3.13.7 dart-lang/sdk#64723.
• Fix: the previous frame's cells are resolved into a nullable local before the loop.
• Regression test: test/integration/aot_render_test.dart AOT-compiles a small renderDiff driver and runs it. It fails on the 1.64.2 code with the reported crash and takes about 2 s.

Fixed: a bare Esc did nothing in :ide and the dashboard

• A lone ESC byte stayed buffered in KeyDecoder until another key arrived. A new LoneEscapeTimer, shared by both apps, delivers it as Escape after 50 ms with no more input. Escape sequences split across two reads still decode.

Added: node Info tab in the dashboard

• An opened node has Sessions · Info · Credentials tabs (s / i / c). i on the node list opens a node straight onto Info. Esc on any of them goes back to the node list.
• Info shows identity, OS, OS version, arch, CPUs, hostname, agent version compared with this client, Dart runtime, capabilities, labels and the connection. It scrolls, wraps long values by column (emoji-safe), and r refreshes it.
• Sessions shows a one-line node summary instead of duplicating Info, and only loads sessions when they haven't been loaded yet.
• PlatformInfo gains optional osVersion, cpuCount and runtimeVersion, left out of the JSON when unknown. Older nodes and Hubs keep working, and the tab shows "not reported" for them. :info shows the new fields too.

Security: node-supplied text can't inject terminal escapes

• ScreenBuffer paints control characters (C0, DEL, C1) as � and :info strips them. Before this, a hostile node's hostname, labels or OS version could clear the screen, set the window title or write to the clipboard on the user's terminal.

Review fixes

I ran a high-effort review of the branch and addressed 9 of its 10 findings:

• a stale background credentials load could land on another node or tab
• Esc on Info triggered an RPC instead of going back
• long label keys were truncated
• a label keyed Status was colored like the node's status
• wrapping split surrogate pairs
• switching back to Sessions re-fetched sessions every time
• node detail was built in two places
• the Esc-timer logic was duplicated in both apps
• the terminal-escape issue above

I skipped one: tagging the AOT test as opt-in. It runs in about 2 s, and a tag would stop default CI from running it.

Bumps to 1.65.0 (1.64.2 was tagged) with CHANGELOG entries.

Test plan

• The AOT regression test fails on the 1.64.2 code and passes on the fix
• Dashboard: Info content and wrapping, "not reported" for older agents, scroll plus refresh, a node dropping out of the list, tab navigation with sessions loaded once, Esc leaving from Info and Credentials with no RPC, a stale credentials load dropped, long label keys, emoji wrapping, no Status color on labels, a split arrow key not taken for Escape
• ScreenBuffer control-character tests, :info stripping, LoneEscapeTimer unit tests, PlatformInfo round-trip and wire shape
• format, analyze --fatal-infos, dependency_validator and pub publish --dry-run all clean
• test/unit (1231) and test/integration (298) pass locally
