fix(typebox): migrate to v1 with extension compat (#3474 )

* fix(typebox): migrate to v1 with extension compat

Replace AJV-based validation with TypeBox-native validation, keep legacy extension imports working (including @sinclair/typebox/compiler), and restore coercion for serialized/plain JSON schemas.

This change closes #3112.

* fix(typebox): use canonical imports and harden coercion

Switch first-party code to canonical typebox imports while retaining legacy extension aliases in the loader.

Remove obsolete runtime codegen guards, expand serialized JSON-schema coercion coverage, and update related tests and fixtures.

Fixes #3112.

fix(coding-agent): do not inject bunfs script path into subagent prompts (#3002 )

The presence of `process.argv[1]` in the current invocation does not
imply that the current `pi` process is being invoked as a script.
Specifically, in the case of a bun compiled binary, `process.argv[1]`
will be the virtual path `/$bunfs/root/pi`, which is not a real file on
the filesystem.  This causes the subagent extension to inject this path
into the child `pi` invocation, which is interpreted as part of the
prompt, which confuses the subagent.

This change uses the script only if it is not a bunfs virtual script

fix(subagent): list available agents in unknown-agent error (#1414 )

The invalid-params error paths already listed available agents,
but the unknown-agent path in runSingleAgent just returned
'Unknown agent: claude' with no hint what exists.

Now: 'Unknown agent: "claude". Available agents: "worker".'

Model would guess names like "claude", "default", or skill names
like "brave-search". Now it self-corrects on the next call.

Tested with Opus 4.6: without fix, model gave up on subagent
and ran the tool calls itself instead. With fix, 1 wasted call.

fix(coding-agent): align ToolDefinition.execute signature with AgentTool

BREAKING CHANGE: ToolDefinition.execute parameter order changed from
(id, params, onUpdate, ctx, signal) to (id, params, signal, onUpdate, ctx).

This aligns with AgentTool.execute so wrapping built-in tools no longer
requires parameter reordering. Update extensions by swapping signal and
onUpdate parameters.
