feat(agent-core): custom agent files and secondary model on the v1 engine (#2232)
* feat(agent-core): custom agent files and secondary model on the v1 engine

Migrate the custom agentfile and secondary-model capabilities from
agent-core-v2 to the v1 engine so they work in the TUI and plain
kimi -p sessions:

- discover Markdown agent files from user/project/extra/explicit
  directories with the v2 precedence rules, a merged session profile
  catalog replacing the hardcoded builtin profile lookups, SYSTEM.md
  main prompt override, and ${base_prompt} backed by the effective
  default
- --agent/--agent-file now work in print mode on the default engine;
  CreateSessionOptions gains agentProfile/agentFiles
- [secondary_model] config + KIMI_SECONDARY_MODEL/EFFORT bind newly
  spawned subagents to a cheaper model behind the secondary-model
  experiment flag, with primary/secondary model params on Agent and
  AgentSwarm and upfront session warnings
- full disallowedTools deny semantics (exact names + mcp__ globs)
  evaluated by the tool manager and persisted in the agent wire

* fix(cli): guard optional agentFiles in the prompt runner

runPrompt is also driven programmatically (headless goal flow) with
options that never pass through the CLI parser defaults, so agentFiles
can be undefined; mirror the addDirs optional-chaining pattern. Also
extend the SDK experimental-feature assertion with the secondary-model
flag.

* fix(agent-core): preserve custom agent bindings on v1

* fix(agent-core): narrow secondary model error hints

* fix(agent-core): persist custom agent profile bindings

* Delete .changeset/sdk-agent-profile-options.md

* fix(agent-core): keep SYSTEM.md a prompt-only overlay for delegation

* docs: update agent file and secondary model availability wording

* fix(cli): reject --agent-file combined with session resume

The resume path only forwards the agent file's name for the bound-profile
assertion; the file's content is never re-applied (the session keeps its
creation-time catalog snapshot). Previously the combination was silently
accepted, so an edited file (or a same-named one) appeared to apply but did
not. Reject it at option validation and document the constraint.

* refactor(agent-core): share prompt-section prose and note v2 twins in agentfile headers

The Windows notes, additional-dirs and skills prose blocks existed twice:
inline in the builtin default template (system.md) and as constants in the
agent-file renderer (from-file.ts). Extract them to profile/prompt-sections.ts
as the single source: system.md renders them through injected KIMI_* template
variables and from-file.ts imports the same constants. Rendered prompts are
byte-identical for all four builtin profiles across macOS/Windows and
skills/dirs on/off; a new test pins system.md to the shared constants.

Also mark each profile/agentfile file with the path of its agent-core-v2
counterpart so format/semantics changes land in both engines.

* feat(cli): add /secondary_model command for the subagent model

Mirror /model: a picker with a thinking-effort step that persists [secondary_model] and live-applies to the current session via a new Session.setSecondaryModel RPC (node-sdk wrapper included), so newly spawned subagents bind the new model right away. The /model picker now hides the synthesized __secondary__ derived entry; docs and the update-config builtin skill mention the section.

* feat(tui): show the bound model in subagent run stats

Subagents report their model alias via agent.status.updated after spawn; resolve it to a display name and surface it in tool-call subagent stats and agent-group rows.

* fix(agent-core): validate agent profile before session persistence

* fix(agent-core): refresh subagent tools after model switch

* fix(agent-core): show subagent model preferences

* fix(agent-core): preserve secondary model recipe on live apply

* fix(agent-core): make secondary model apply explicit

* fix(tui): refresh secondary model display state

* chore: merge secondary model changesets into one

* Add /secondary_model command for subagent configuration

Show each subagent's model in the subagent card header and agent-group rows. Requires the secondary-model experiment (KIMI_CODE_EXPERIMENTAL_SECONDARY_MODEL=1); run /secondary_model to pick a model and thinking effort, applied to the current session immediately.

* fix(agent-core): align explicit agent file precedence

* fix(agent-core): let disallowedTools deny select_tools

* chore(cli): drop engine mention from --agent/--agent-file help text

* feat(cli): support --agent/--agent-file in the interactive TUI

Bind the selected agent profile to the startup session when launching
the TUI with --agent/--agent-file, including the session created after
an OAuth login at startup. Sessions created later in the process (/new)
keep the default profile.

Make both flags creation-only in every mode: combining them with
--session/--continue is now rejected in print mode too, since resume
restores the bound agent from the session automatically.

* fix(agent-core): persist new secondary-model selections under env overrides

stripSecondaryModelConfig restored secondary_model.model/default_effort
from raw whenever KIMI_SECONDARY_MODEL/KIMI_SECONDARY_EFFORT was set, so
a /secondary_model pick made under the env vars was silently discarded
on write. Restore from raw only when the value being written still
equals the env value (an overlay round-trip), mirroring the pointer
check in stripEnvModelConfig; a genuinely different selection now
reaches config.toml.

* fix(cli): report the effective secondary model when env overrides the pick

/secondary_model toasted the picked alias even when
KIMI_SECONDARY_MODEL/KIMI_SECONDARY_EFFORT made the session bind a
different model. Read the effective binding back from the reloaded
config (as /model does from session status) and warn with the
env-overridden values instead.

* feat(tui): show the bound model name in the AgentSwarm panel header
