Pins the T3 contract from 9e12eca to 40c3682. Two upstream commits:

• fix: chat file links open the file agents cite pingdotgg/t3code#33943: runtime_info now asks agents to link every file they cite, not only the files they produce, by absolute path, with a line example [http.ts:42](/abs/path/http.ts:42). The T3 audit behind it found 24% of Claude's chat file links broken, mostly inline paths relative to a package or to another checkout. Clients now also fall back to the one workspace file a relative link is the suffix of.
• fix(claude): version errors from a custom endpoint no longer say to run claude update pingdotgg/t3code#34176: version errors from a custom ANTHROPIC_BASE_URL no longer say to run claude update.

Two contract files changed: runtimeInstructions.ts (the runtime_info text) and ClaudeSkills.ts (a new customClaudeApiEndpointHost helper).

Breaks a mapping

• T3's injected file-link instruction changed. The "Files in the reply" item in skills/poteto-mode/references/t3-adapter.md now covers the file:line citations that why and blast-radius ask for, puts the line number in the label and the absolute target, and says why a relative path breaks. No tool was renamed or removed.

Version 0.13.9 to 0.13.10.
