3008f083ca [aidan] feat: scheduled tasks (#105)
* [eric] ci: gitleaks-ignore the known historical secrets so our branch stops failing on leaks it didnt add

* [eric] workflows: restore scheduled-tasks on the workflow line (revert removal, keep windows fixes + 1.1.69)

* [eric] workflows: re-apply uncommitted scheduling wip (schedule pill, calendar view, slice)

* [eric] ops: gitignore dev-team local state files

* [eric] ops: backlog item for download-tracking visibility

* [eric] ci: allowlist the cdp-routes redaction-test token in gitleaks

* [aidan] feat/scheduled-tasks: keep step labels in sync on edit and show chevron on every step

* [aidan] fix: schedule time in chat

* [aidan] ux/workflows: add workflow step removal (#91)

* [aidan] feat/scheduled-tasks: remember workflow tool permissions across runs

* [aidan] feat/task-scheduling: add hourly and minute (15-min minimum) schedule intervals (#93)

* [aidan] feat/scheduled-tasks: calendar, rename, and edit workflows (#94)

* [aidan] bug: fix schedule button

* [aidan] fix/agent-errors: surface provider rate limits

* [aidan] ux/cards: click-to-rename for chat and workflow titles

Single-click a card's title to enter edit mode inline. Commit on Enter/blur,
cancel on Escape. Rename persists via PATCH for workflows and sessions.

* [aidan] feat/workflows: seed build prompt for zero-step workflows

When a new workflow has no steps, seed the agent with a prompt asking
the user to describe what the workflow should do, rather than starting blank.

* [aidan] feat/workflows: add-to-schedule popover for unscheduled workflows

Clicking the "+" on an unscheduled workflow row opens a popover with two options:
- Keep this schedule: enables the workflow's existing cadence and moves it to Scheduled
- Change schedule: opens the scheduling editor to pick a different time

* [aidan] ux/workflows: wire add-to-schedule popover and simplify New button

- Made the "+" icon on unscheduled workflow rows clickable, opening a popover
  to keep or change the schedule
- Removed AddIcon from toolbar "New" button (now reads "New" instead of "+ New")

* [aidan] fix/scheduled-tasks: open schedule calendar when Schedule pill clicked

Fixed the Schedule pill click being swallowed by the toolbar's dismiss handler.
Exempted the toolbar pills via data-toolbar-pills so their click handlers fire.

* [aidan] ux/workflows: open New workflow in agent build chat instead of empty card

When creating a new workflow from the hub, open it in edit_agent view (with the
agent builder chat) instead of a preview card. The workflow is created on the
backend first so the embedded session has a real ID.

* [aidan] feat/workflow-edit: add draft testing save flow

* [aidan] ux/chat: remove continue chat button

* [aidan] ux/workflows: polish workflow card interactions

* [aidan] fix/workflow-scheduling: save unscheduled workflows as drafts

* aidan ui: schedule naming changes

* [aidan] ui: tool calling desc/naming

* [aidan] ui: calendar sidebar naming

* [aidan] ui: fix stop viewing closing chat

* [aidan] feat/workflows: auto-name workflows and polish the build flow (#95)

* [aidan] feat/workflow-auto-naming: auto-generate workflow titles from steps

Generate a title + description from a workflow's steps (one aux call,
reused for step labels) whenever it is still auto_named, so a workflow
built in the Edit Agent names itself on commit instead of staying
"New workflow". A manual rename sets auto_named=False and is never
overwritten. Stream the aux call (non-streaming drops content on some
9router lanes) and fall back to a step-derived title when the model is
unavailable.

* [aidan] feat/workflows: hide unsaved new workflows until first save

A brand-new "+ New" workflow is created with unsaved=true and kept out
of the hub's scheduled/unscheduled lists while the user is still building
it in the Edit Agent. The first commit (Save) clears the flag and the
workflow appears. Every other create path stays visible immediately.

* [aidan] ux/workflows: remove redundant save workflow button

The Edit Agent already has Discard/Save controls in its strip, so the
header "Save Workflow" button was a duplicate save path. Remove it and
its pulse/edit-session-id wiring; the model/time subtitle stays.

* [aidan] ux/workflows: animate title on auto-rename

Wrap the workflow card title in the same Typewriter the chat card uses,
so when the auto-generated name replaces the placeholder after Save it
retypes letter-by-letter. Gated on a real (non-placeholder) title so it
never animates on mount or for already-named workflows.

* [aidan] ux/workflows: animate sidebar title on auto-rename

Wrap the calendar hub's sidebar row title in the same Typewriter the
workflow card uses, so a title that auto-renames retypes letter-by-letter
in the sidebar too. Extract the placeholder/isRealTitle guard into the
shared workflowVisuals so the card and sidebar stay in sync.

* [aidan] fix/workflows: connect watch tether, keep watched chat open, wire draft run/history

* [aidan] ui: grey out chat pill when not selected

* [aidan] ui: fix running agent display

* [aidan] feat/workflows: toast when an unattended scheduled run starts

* [aidan] feat/workflows: validate steps before scheduling and keep chat tool memory

* [aidan] feat/mcp-suggestions: dismissable integration banner with per-session cooldown

* [aidan] ux/workflows: surface paused state on card, sidebar, and calendar; tidy run history

* [aidan] feat/mcp-suggestions: suggest both Google and Microsoft when provider is ambiguous

* [aidan] fix/agent-tokens: friendly out-of-tokens card across all agent surfaces

* [aidan] feat/workflow-model: persist edit-agent model on save with switch notice and fresh drafts

* [aidan] fix/workflow-chat: force stop on watched run mirrors workflow card stop

* [aidan] fix/workflow-cards: keep watched run tethered on finish to avoid duplicate chat

* [aidan] feat/schedule-calendar: mark current time with a now line in week view

* [aidan] refactor/private-names: rename error and schedule classifiers from _ to p_

* [aidan] feat/scheduled-tasks: agent workflow scheduling and in-chat convert (#98)

* [aidan] feat/workflow-suggest: nudge user to convert repeatable chat to workflow

Add SuggestConvertToWorkflow MCP tool that agents call at the end of a task
when they've completed something worth repeating (daily report, weekly check,
recurring data pull). Frontend detects the tool call and glows the "Convert to
workflow" button 3 times to draw the eye. When user clicks it, the suggested
cadence (e.g. "every weekday at 9am") is stored in the draft and seeded into
the scheduling agent's first prompt, so the agent can act on the suggestion
rather than asking the user again.

Tool is never auto-called — agents decide when a task is genuinely repeatable
(not debugging, creative work, one-off lookup). Tool description emphasizes
sparse, high-confidence use only (once per session max).

Files changed:
- backend/apps/agents/schedule_mcp_server.py: add SuggestConvertToWorkflow tool
- frontend/src/shared/mcpToolMeta.ts: add label for new tool
- frontend/src/app/pages/Dashboard/cards/AgentCard.tsx: detect suggestion in
  session messages, show+glow "Convert to workflow" button, pass cadence to draft
- frontend/src/shared/state/workflowsSlice.ts: add suggested_cadence field to
  Workflow interface
- frontend/src/app/pages/Workflows/SchedulingView.tsx: seed scheduling agent
  prompt with suggested cadence hint
