Nikolas de Hor 808064e26b fix: detect tilde paths in restrictToWorkspace shell guard
_extract_absolute_paths() only matched paths starting with / or drive
letters, missing ~ paths that expand to the home directory. This
allowed agents to bypass restrictToWorkspace by using commands like
cat ~/.nanobot/config.json to access files outside the workspace.

Add tilde path extraction regex and use expanduser() before resolving.
Also switch from manual parent-chain check to is_relative_to() for
more robust path containment validation.

Nikolas de Hor da8a4fc68c fix: prevent cron job execution from scheduling new jobs
When a cron job fires, the agent processes the scheduled message and
has access to the cron tool. If the original message resembles a
scheduling instruction (e.g. "remind me in 10 seconds"), the agent
would call cron.add again, creating an infinite feedback loop.

Add a cron-context flag to CronTool that blocks add operations during
cron job execution. The flag is set before process_direct() and cleared
in a finally block to ensure cleanup even on errors.

Nikolas de Hor ad99d5aaa0 fix: merge consecutive user messages into single message
Some LLM providers (Minimax, Dashscope) strictly reject consecutive
messages with the same role. build_messages() was emitting two separate
user messages back-to-back: the runtime context and the actual user
content.

Merge them into a single user message, handling both plain text and
multimodal (image) content. Update _save_turn() to strip the runtime
context prefix from the merged message when persisting to session
history.

Nikolas de Hor cc8864dc1f fix: remove overly broad "codex" keyword from openai_codex provider
The bare keyword "codex" causes false positive matches when any model
name happens to contain "codex" (e.g. "gpt-5.3-codex" on a custom
provider).  This incorrectly routes the request through the OAuth-based
OpenAI Codex provider, producing "OAuth credentials not found" errors
even when a valid custom api_key and api_base are configured.

Keep only the explicit "openai-codex" keyword so that auto-detection
requires the canonical prefix.  Users can still set provider: "custom"
to force the custom endpoint, but auto-detection should not collide.

Nikolas de Hor 66063abb8c fix: prevent session poisoning from null/error LLM responses
When an LLM returns content: null on a plain assistant message (no
tool_calls), the null gets saved to session history and causes
permanent 400 errors on every subsequent request.

- Sanitize None content on plain assistant messages to "(empty)" in
  _sanitize_empty_content(), matching the existing empty-string handling
- Skip persisting error responses (finish_reason="error") to the
  message history in _run_agent_loop(), preventing poison loops

Nikolas de Hor 4303026e0d fix: break Discord typing loop on persistent HTTP failure
The typing indicator loop catches all exceptions with bare
except/pass, so a permanent HTTP failure (client closed, auth
error, etc.) causes the loop to spin every 8 seconds doing
nothing until the channel is explicitly stopped.

Log the error and exit the loop instead, letting the task
clean up naturally.

Nikolas de Hor 4cbd857250 fix: handle edge cases in message splitting and send failure
- _split_message: return empty list for empty/None content instead
  of a list with one empty string (Discord rejects empty content)
- _split_message: use pos <= 0 fallback to prevent empty chunks
  when content starts with a newline or space
- _send_payload: return bool to indicate success/failure
- send: abort remaining chunks when a chunk fails to send,
  preventing partial/corrupted message delivery

Nikolas de Hor f19baa8fc4 fix: convert remaining f-string logger calls to loguru native format
Follow-up to #864. Three f-string logger calls in base.py and dingtalk.py
were missed in the original sweep. These can cause KeyError if interpolated
values contain curly braces, since loguru interprets them as format placeholders.

Nikolas de Hor 73530d51ac fix: store session key in JSONL metadata to avoid lossy filename reconstruction
list_sessions() previously reconstructed the session key by replacing all
underscores in the filename with colons. This is lossy: a key like
'cli:user_name' became 'cli:user:name' after round-tripping.

Now the actual key is persisted in the metadata line during save() and read
back in list_sessions(). Legacy files without the key field fall back to
replacing only the first underscore, which handles the common channel:chat_id
pattern correctly.

Nikolas de Hor 4c75e1673f fix: split Discord messages exceeding 2000-character limit
Discord's API rejects messages longer than 2000 characters with HTTP 400.
Previously, long agent responses were silently lost after retries exhausted.

Adds _split_message() (matching Telegram's approach) to chunk content at
line boundaries before sending. Only the first chunk carries the reply
reference. Retry logic extracted to _send_payload() for reuse across chunks.

Nikolas de Hor 37222f9c0a fix: add connecting guard to prevent concurrent MCP connection attempts
Addresses Codex review: concurrent callers could both pass the
_mcp_connected guard and race through _connect_mcp(). Added
_mcp_connecting flag set immediately to serialize attempts.

Nikolas de Hor 45f33853cf fix: only apply interim fallback when no tools were used
Addresses Codex review: if the model sent interim text then used tools,
the interim text should not be used as fallback for the final response.

Nikolas de Hor 44f44b305a fix: move MCP connected flag after successful connection to allow retry
The flag was set before the connection attempt, so if any MCP server
was temporarily unavailable, the flag stayed True and MCP tools were
permanently lost for the session.

Nikolas de Hor 4eb07c44b9 fix: preserve interim content as fallback when retry produces empty response
Fixes regression from #825 where models that respond with final text

Nikolas de Hor c86dbc9f45 fix: wait for killed process after shell timeout to prevent fd leaks
When a shell command times out, process.kill() is called but the
process object was never awaited after that. This leaves subprocess
pipes undrained and file descriptors open. If many commands time out,
fd leaks accumulate.

Add a bounded wait (5s) after kill to let the process fully terminate
and release its resources.

Nikolas de Hor 1b49bf9602 fix: avoid duplicate messages on retry and reset final_content
Address review feedback:
- Remove on_progress call for interim text to prevent duplicate
  messages when the model simply answers a direct question
- Reset final_content to None before continue to avoid stale
  interim text leaking as the final response on empty retry

Nikolas de Hor 464352c664 fix: allow one retry for models that send interim text before tool calls
Some LLM providers (MiniMax, Gemini Flash, GPT-4.1, etc.) send an
initial text-only response like "Let me investigate..." before actually
making tool calls. The agent loop previously broke immediately on any
text response without tool calls, preventing these models from ever
using tools.

Now, when the model responds with text but hasn't used any tools yet,
the loop forwards the text as progress to the user and gives the model
one additional iteration to make tool calls. This is limited to a
single retry to prevent infinite loops.

Nikolas de Hor 33d760d312 fix: handle /help command directly in Telegram, bypassing ACL check
The /help command was routed through _forward_command → _handle_message
→ is_allowed(), which denied access to users not in the allowFrom list.
Since /help is purely informational, it should be accessible to all
users — similar to how /start already works with its own handler.

Add a dedicated _on_help handler that replies directly without going
through the message bus access control.

Nikolas de Hor 107a380e61 fix: prevent duplicate memory consolidation tasks per session
Add a `_consolidating` set to track which sessions have an active
consolidation task. Skip creating a new task if one is already in
progress for the same session key, and clean up the flag when done.

This prevents the excessive API calls reported when messages exceed
the memory_window threshold — previously every single message after
the threshold triggered a new background consolidation.
