The extension system currently only forwards agent_start, agent_end,
turn_start, and turn_end events. This means extensions cannot access
streaming text (token-by-token), message lifecycle, or tool execution
progress — all of which are available to internal subscribers.
This adds forwarding for the remaining 6 agent event types:
- message_start, message_update, message_end
- tool_execution_start, tool_execution_update, tool_execution_end
These follow the exact same pattern as the existing forwarded events:
new interfaces in types.ts, exports in index.ts, and else-if blocks
in _emitExtensionEvent(). The new types are included in ExtensionEvent
and automatically flow through RunnerEmitEvent (they're not in the
exclusion list).
This enables extensions to build real-time UIs, streaming WebSocket
bridges, and other integrations that need fine-grained event access.

After compaction, context token count is unknown until the next LLM
response. Instead of showing stale pre-compaction values or heuristic
estimates, the footer now shows ?/200k.
ContextUsage.tokens and ContextUsage.percent are now number | null
(breaking change). Removed usageTokens, trailingTokens, lastUsageIndex
from ContextUsage (internal details).
Also fixed _checkCompaction() using .find() (first compaction) instead
of getLatestCompactionEntry() (latest), which caused incorrect overflow
detection with multiple compactions.
Closes#1382
Update extensions.md and rpc.md to accurately reflect that ctx.hasUI is
true in RPC mode. Document missing unsupported/degraded ExtensionUIContext
methods: pasteToEditor, getAllThemes, getTheme, setTheme.

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.
Include tool parameter names, types, descriptions in a collapsible
section under each tool in the export HTML. Also adds parameters to
pi.getAllTools() return value.

rg was only downloaded lazily when the grep tool was invoked, but the
LLM often uses rg directly via the bash tool. Ensure both fd and rg
are downloaded at startup so they are available in PATH for all tools.
fixes#1348
- Use parametersJsonSchema instead of parameters for Gemini tool declarations
to support full JSON Schema (anyOf, oneOf, const, etc.)
- Keep legacy parameters field for Claude models on Cloud Code Assist, where
the API translates parameters into Anthropic's input_schema
- Revert claude-opus-4-6-thinking back to claude-opus-4-5-thinking (model
doesn't exist on the Antigravity endpoint)
fixes#1398
Windows does not ship with unzip, causing fd/rg download to fail on
first run in PowerShell. Use tar (bsdtar, available on Windows 10+)
for both .tar.gz and .zip extraction. Also adds proper error checking
on the extraction result.
fixes#1348
