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

Browse Source 
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.

Both are stored in `~/.hermes/memories/` and are injected into the system prompt as a frozen snapshot at session start. The agent manages its own memory via the `memory` tool — it can add, replace, or remove entries.
:::info
Character limits keep memory focused. Memory does **not** auto-compact: when a
write would exceed the limit, the `memory` tool returns an error instead of
silently dropping entries. The agent then makes room itself — consolidating or
removing entries in the same turn before retrying (see [What Happens When Memory
is Full](#what-happens-when-memory-is-full)). Note that `replace` is also bound
by the limit: swapping an entry for a longer one can still overflow, so the new
content must be shortened (or another entry removed) to fit.
Character limits keep memory focused. When memory is full, the agent consolidates or replaces entries to make room for new information.

## Controlling memory writes (`write_approval`)
By default the agent saves memory freely — including from the background
self-improvement review that runs after a turn. If you'd rather approve saves
first, set `memory.write_approval: true`. It's a simple on/off gate applied to
**both** foreground turns and the background review:
| `write_approval` | Behaviour |
|------------------|-----------|
| `false` (default) | Write freely — the gate is off (the pre-gate behaviour). |
| `true` | Require approval before anything is saved. In the interactive CLI, foreground writes prompt you inline (entries are small enough to read in full). Everywhere else — messaging platforms, scripts, and the background self-improvement review — writes are **staged** for review with `/memory pending`. |
> To turn memory off entirely (not just gate it), set `memory_enabled: false`.
Review staged writes from the CLI or any messaging platform:
```
/memory pending # list staged memory writes (auto ones tagged [auto])
/memory approve <id> # apply one (or 'all')
/memory reject <id> # drop one (or 'all')
/memory approval on # turn the gate on (or 'off') and persist it
```
This is the answer to "the agent saved a wrong assumption about me": set
`write_approval: true`, and every save — especially the unprompted background
ones — waits for your yes/no before it ever enters your profile.
## Controlling skill writes (`skills.write_approval`)
Skills use the same on/off gate, but the review UX differs because a
`SKILL.md` is far too large to read in a chat bubble:
```yaml
skills:
write_approval: false # false = write freely (default) | true = require approval
```
When `write_approval: true`, skill writes (create / edit / patch / write_file /
delete) always **stage** regardless of origin. You review the one-line gist
inline, but the full diff stays out-of-band:
```
/skills pending # list staged skill writes + a one-line gist each
/skills diff <id> # full unified diff (best viewed in CLI or dashboard)
/skills approve <id> # apply it (or 'all')
/skills reject <id> # drop it (or 'all')
/skills approval on # turn the gate on (or 'off') and persist it
```
On a messaging platform, approve a skill from its gist + metadata, or open
`/skills diff` on the CLI / dashboard / the staged file under
`~/.hermes/pending/skills/<id>.json` when you want to read the whole change.

## External Memory Providers
For deeper, persistent memory that goes beyond MEMORY.md and USER.md, Hermes ships with 8 external memory provider plugins — including Honcho, OpenViking, Mem0, Hindsight, Holographic, RetainDB, ByteRover, and Supermemory.
