Replace the single _processing_lock (asyncio.Lock) with per-session locks
so that different sessions can process LLM requests concurrently, while
messages within the same session remain serialised.
An optional global concurrency cap is available via the
NANOBOT_MAX_CONCURRENT_REQUESTS env var (default 3, <=0 for unlimited).
Also re-binds tool context before each tool execution round to prevent
concurrent sessions from clobbering each other's routing info.
Tested in production and manually reviewed.
(cherry picked from commit c397bb4229e8c3b7f99acea7ffe4bea15e73e957)
* feat: add contextBudgetTokens config field for tool-loop trimming
* feat: implement _trim_history_for_budget for tool-loop cost reduction
* feat: thread contextBudgetTokens into AgentLoop constructor
* feat: wire context budget trimming into agent loop
* refactor: move trim_history_for_budget to helpers and add docs
- Extract trim_history_for_budget() as a pure function in helpers.py
- AgentLoop._trim_history_for_budget becomes a thin wrapper
- Add docs/CONTEXT_BUDGET.md with usage guide and trade-off notes
- Replace wrapper tests with direct helper unit tests

- Fix _read_media_bytes treating local paths as URLs: local file
handling code was dead code placed after an early return inside the
HTTP try/except block. Restructure to check for local paths (plain
path or file:// URI) before URL validation, so files like
/home/.../.nanobot/workspace/generated_image.svg can be read and
sent correctly.
- Add .svg to _IMAGE_EXTS so SVG files are uploaded as file_type=1
(image) instead of file_type=4 (file).
- Add tests for local path, file:// URI, and missing file cases.

Move channel-specific login logic from CLI into each channel class via a
new `login(force=False)` method on BaseChannel. The `channels login <name>`
command now dynamically loads the channel and calls its login() method.
- WeixinChannel.login(): calls existing _qr_login(), with force to clear saved token
- WhatsAppChannel.login(): sets up bridge and spawns npm process for QR login
- CLI no longer contains duplicate login logic per channel
- Update CHANNEL_PLUGIN_GUIDE to document the login() hook

Previously the WeChat channel's send() method only handled text messages,
completely ignoring msg.media. When the agent called message(media=[...]),
the file was never delivered to the user.
Implement the full WeChat CDN upload protocol following the reference
@tencent-weixin/openclaw-weixin v1.0.2:
1. Generate a client-side AES-128 key (16 random bytes)
2. Call getuploadurl with file metadata + hex-encoded AES key
3. AES-128-ECB encrypt the file and POST to CDN with filekey param
4. Read x-encrypted-param from CDN response header as download param
5. Send message with the media item (image/video/file) referencing
the CDN upload
Also adds:
- _encrypt_aes_ecb() for AES-128-ECB encryption (reverse of existing
_decrypt_aes_ecb)
- Media type detection from file extension (image/video/file)
- Graceful error handling: failed media sends notify the user via text
without blocking subsequent text delivery

During testing, we discovered that when a user requests the agent to
send a file (e.g., "send me IMG_1115.png"), the agent would call
read_file to view the content and then reply with text claiming
"file sent" — but never actually deliver the file to the user.
Root cause: The system prompt stated "Reply directly with text for
conversations. Only use the 'message' tool to send to a specific
chat channel", which led the LLM to believe text replies were
sufficient for all responses, including file delivery.
Fix: Add an explicit IMPORTANT instruction in the system prompt
telling the LLM it MUST use the 'message' tool with the 'media'
parameter to send files, and that read_file only reads content
for its own analysis.

Add a new WeChat (微信) channel that connects to personal WeChat using
the ilinkai.weixin.qq.com HTTP long-poll API. Protocol reverse-engineered
from @tencent-weixin/openclaw-weixin v1.0.2.
Features:
- QR code login flow (nanobot weixin login)
- HTTP long-poll message receiving (getupdates)
- Text message sending with proper WeixinMessage format
- Media download with AES-128-ECB decryption (image/voice/file/video)
- Voice-to-text from WeChat + Groq Whisper fallback
- Quoted message (ref_msg) support
- Session expiry detection and auto-pause
- Server-suggested poll timeout adaptation
- Context token caching for replies
- Auto-discovery via channel registry
No WebSocket, no Node.js bridge, no local WeChat client needed — pure
HTTP with a bot token obtained via QR code scan.

Trigger token consolidation before prompt usage reaches the full context window so response tokens and tokenizer estimation drift still fit safely within the model budget.

Register Mistral as a first-class provider with LiteLLM routing,
MISTRAL_API_KEY env var, and https://api.mistral.ai/v1 default base.
Includes schema field, registry entry, and tests.
- Add strip_think() to helpers.py as single source of truth
- Filter deltas in agent loop before dispatching to consumers
- Implement send_delta in TelegramChannel with progressive edit_message_text
- Remove duplicate think filtering from CLI stream.py and telegram.py
- Remove legacy fake streaming (send_message_draft) from Telegram
- Default Telegram streaming to true
- Update CHANNEL_PLUGIN_GUIDE.md with streaming documentation

Move ThinkingSpinner and StreamRenderer into a dedicated module to keep
commands.py focused on orchestration. Uses Rich Live with manual refresh

The build_messages() method was missing the current_role parameter that
loop.py calls with, causing a TypeError at runtime. This restores the
parameter with its default value of "user" to match the original PR #2104.
- Restore enable attribute to ExecToolConfig
- Remove deprecated memory_window field (was removed in f44c4f9 but brought back by cherry-pick)
- Restore exclude=True on openai_codex and github_copilot oauth providers
The tz parameter was previously only allowed with cron_expr. When users
specified tz with at for one-time tasks, it returned an error. Now tz
works with both cron_expr and at — naive ISO datetimes are interpreted
in the given timezone via ZoneInfo.
- Relax validation: allow tz with cron_expr or at
- Apply ZoneInfo to naive datetimes in the at branch
- Update SKILL.md with at+tz examples
- Add automated tests for tz+at combinations

Without this flag, a BaseException (e.g. CancelledError from /stop)
in one tool would propagate immediately and discard results from the
other concurrent tools, corrupting the OpenAI message format.
With return_exceptions=True, all tool results are collected; any
exception is converted to an error string for the LLM.

Tool calls from a single LLM response are independent by design —
the model batches them precisely because they can run concurrently.
Replace the serial for-loop with asyncio.gather so N tools complete
in max(time_i) instead of sum(time_i).

Resolve conflict in context.py: keep main's build_messages which already
merges runtime context into user message (achieving the same cache goal).
The real value-add from this PR is the second cache breakpoint in
litellm_provider.py.
