opentui(phase3): launcher integration — HERMES_TUI_ENGINE dual-engine

hermes --tui launches the native OpenTUI engine (Bun) when
HERMES_TUI_ENGINE=opentui (env) or display.tui_engine=opentui (config);
Ink stays the default and the shipping path is untouched.

- _resolve_tui_engine() (env > config > ink); refuses opentui on
  Windows/Termux (no Bun) -> falls back to ink with a notice.
- _make_opentui_argv() -> [bun, src/entry.real.tsx] (no build step).
- _bun_bin() with HERMES_BUN override.
- Branch at top of _make_tui_argv BEFORE _ensure_tui_node (Bun-only host
  must not bootstrap Node).
- Gate _launch_tui NODE_OPTIONS/--max-old-space-size on engine==ink (Bun
  is JSC; the V8 flag errors/ignores).

Verified end-to-end via tmux: real hermes --tui -> Bun -> OpenTUI ->
real Python gateway streamed a real reply. No-flag default still ink.

types, but both preserve the action name in the message.

"""Coding-context awareness — base Hermes, every interactive surface.
When the user runs Hermes inside a code workspace (CLI, TUI, desktop app, or an
editor over ACP), Hermes shifts into a **coding posture**. This module is the
single place that decides whether we're in that posture and what it implies,
so the rest of the codebase never re-derives "are we coding?" on its own.
Architecture one seam, many consumers
----------------------------------------
The posture is modelled as a frozen :class:`RuntimeMode` selected from a small
:class:`ContextProfile` registry (today: ``coding`` and ``general``). A profile
is *data* it declares the toolset to collapse to, the operating brief to
inject, and hints for other domains (model routing, memory, subagents). Every
domain reads the same resolved object instead of probing git/config itself:
* **System prompt** ``RuntimeMode.system_blocks()`` the operating brief +
a live git/workspace snapshot (``agent/system_prompt.py``).
* **Toolset** ``RuntimeMode.toolset_selection()`` the ``coding`` toolset
plus the user's enabled MCP servers (``cli.py`` / ``tui_gateway``). Only
under the opt-in ``focus`` mode: the default posture is prompt-only and
never touches the user's configured toolsets (toolsets like messaging /
smart-home / music are off-by-default anyway, and someone who explicitly
enabled image-gen or Spotify shouldn't lose it for being in a git repo).
* **Delegation** subagents inherit the parent's toolset and run through the
same prompt builder, so the coding posture propagates to children for free.
* **Model / memory / compression** declared on the profile
(``model_hint``, ``memory_policy``) as the extension seam; consumers read
``mode.profile`` rather than re-deciding.
Cache safety
------------
The mode is resolved **once** and is immutable. The workspace snapshot is built
once at prompt-build time and baked into the *stable* system-prompt tier never
re-probed per turn (that would shatter the prompt cache). Branch and dirty state
drift mid-session, so the brief tells the model to re-check with ``git`` before
acting on the snapshot. A ``/coding`` flip therefore only takes effect next
session (deferred), the same contract as ``/skills install`` vs ``--now``.
Activation (config ``agent.coding_context``):
* ``auto`` (default) posture (brief + snapshot) on an interactive coding
surface sitting in a code workspace (git repo or recognised project root).
Prompt-only; toolsets and the skill index untouched.
* ``focus`` like ``auto``, but additionally collapses the toolset to the
``coding`` set + enabled MCP servers and demotes non-coding skill
categories to names-only in the prompt's skill index (no skill is ever
hidden). Explicit opt-in for a lean schema.
* ``on`` force the posture anywhere (incl. non-workspaces). Prompt-only.
* ``off`` disable entirely.

# ── Thinking block signature recovery ─────────────────
# Anthropic signs thinking blocks against the full turn

# content. Any upstream mutation (context compression,
# session truncation, message merging) invalidates the

# signature" or "cannot be modified"). Recovery strips
# ``reasoning_details`` so the retry sends no thinking
# blocks at all. One-shot per outer loop.
#
# The strip targets ``api_messages``, which is the
# API-call-time list that ``_build_api_kwargs`` consumes
# on every retry. ``api_messages`` was populated once at
# the start of the turn from shallow copies of
# ``messages``, so mutating it does not touch the
# canonical store. The previous implementation popped
# ``reasoning_details`` from ``messages`` instead, which
# had two problems: ``api_messages`` carried its own
# reference to the field through the shallow copy, so the
# retry's wire payload still included thinking blocks and
# the recovery never reached the API; and the mutation
# persisted into ``state.db`` through any subsequent
# ``_persist_session`` call, permanently corrupting the
# conversation. Future turns would replay the stripped
# state, hit the same 400, and the agent would terminate
# with ``max_retries_exhausted``, often spawning
# cascading compaction-ended sessions chained off the
# corrupted parent.
# signature → HTTP 400. Recovery: strip reasoning_details
# from all messages so the next retry sends no thinking
# blocks at all. One-shot — don't retry infinitely.

(everything after the main tool-calling ``while`` loop) is lifted here verbatim:
budget-exhaustion summary, trajectory save, session persist, turn diagnostics,
response transforms, result-dict assembly, steer drain, and the memory/skill

Behavior-neutral: the body is moved unchanged. All ``agent.*`` side effects fire
exactly as before; only the post-loop *locals* are passed in as keyword args, and
the assembled ``result`` dict is returned to ``run_conversation`` which returns it
to the caller. The function is synchronous with a single return mirroring the
region it replaces (no awaits, no early returns).
Module ``logger`` is imported lazily inside the body (``from
agent.conversation_loop import logger``) so this module never imports
``agent.conversation_loop`` at import time -> no import cycle, and the log records
keep the exact logger name (``"agent.conversation_loop"``).
