Implement priority-grouped gantt view with table layout

[Copilot]

The gantt command suffered from poor UX: fake 2-week bars for specs without due dates, timeline starting from creation dates (cluttering the past), no priority grouping, and 4 lines per spec with redundant metadata.

Changes

Rewrote src/commands/gantt.ts following Option A (Simplified Timeline):

• Priority grouping: CRITICAL → HIGH → MEDIUM → LOW sections with counts
• Table layout: Fixed 43-char spec column + variable timeline column (weeks × 8 chars), matching alignment patterns from stats.ts and timeline.ts
• Timeline focus: Starts from today, shows "(no due date set)" placeholder instead of fabricated bars
• Information density: 1 line per spec (down from 4), status emoji merged into spec name
• Temporal context: Calendar dates in header, "Today" marker at current week boundary

Example output:

📅 Gantt Chart (4 weeks from Nov 2, 2025)

Spec                                         Timeline
                                             Nov 2   Nov 9   Nov 16  Nov 23

Original prompt

let's implement gantt-ux-improvements as well

[Chronological Review: The conversation began with the user expressing a desire to implement "console-log-chalk-security." The user then delegated this task to a cloud agent. Following that, the user requested to implement "gantt-ux-improvements" as well. The conversation has focused on these two implementation requests.]

[Intent Mapping:

1. "let's implement console-log-chalk-security" - User wants to add a specific feature related to console logging with chalk.
2. "@cloud Delegate: 'Delegate to cloud agent'" - User is delegating the task to a cloud agent for execution.
3. "let's implement gantt-ux-improvements as well" - User wants to implement improvements related to Gantt charts.]

[Technical Inventory:

• Console-log-chalk-security: A feature likely involving enhanced logging capabilities using the chalk library for color formatting in console outputs.
• Gantt-ux-improvements: Enhancements aimed at improving the user experience of Gantt charts, possibly involving UI/UX design changes.]

[Code Archaeology: No specific files or code changes have been discussed or modified yet, as the conversation is still in the planning phase for the implementations.]

[Progress Assessment:

• Completed Tasks: None yet, as the user has only expressed intentions to implement features.
• Partially Complete Work: The delegation to the cloud agent is pending execution.
• Validated Outcomes: None yet, as no features have been implemented or tested.]

[Context Validation: All critical information for continuation is captured, including the specific features to be implemented and the delegation to the cloud agent.]

[Recent Commands Analysis:

• Last Agent Commands:
  1. "let's implement console-log-chalk-security" - User command to initiate a feature implementation.
  2. "@cloud Delegate: 'Delegate to cloud agent'" - Command to delegate the task.
  3. "let's implement gantt-ux-improvements as well" - User command to initiate another feature implementation.
• Tool Results Summary: No specific tool results were returned as the commands were primarily user requests and delegation.
• Pre-Summary State: The agent was actively working on delegating the tasks to the cloud agent when the token budget was exceeded.
• Operation Context: The user is focused on implementing two features, indicating a need for enhanced logging and improved Gantt chart UX.]

1. Conversation Overview: - Primary Objectives: 1. "let's implement console-log-chalk-security" - User wants to add a logging feature. 2. "@cloud Delegate: 'Delegate to cloud agent'" - User delegates the task to a cloud agent. 3. "let's implement gantt-ux-improvements as well" - User wants to implement Gantt chart improvements. - Session Context: The conversation has revolved around the implementation of two specific features, with a focus on delegating tasks to a cloud agent. - User Intent Evolution: The user initially focused on logging improvements and then expanded the scope to include Gantt chart enhancements.

2. Technical Foundation:

• Console-log-chalk-security: A feature for enhanced console logging using the chalk library.
• Gantt-ux-improvements: Enhancements for user experience in Gantt charts.

3. Codebase Status:

• No specific files or code changes have been discussed yet, as the conversation is still in the planning phase.

4. Problem Resolution:

• Issues Encountered: None reported yet.
• Solutions Implemented: None yet, as the conversation is still in the planning phase.
• Debugging Context: No ongoing troubleshooting efforts or known issues.
• Lessons Learned: No insights or patterns have been discovered yet.

5. Progress Tracking:

• Completed Tasks: None yet.
• Partially Complete Work: Delegation to the cloud agent is pending execution.
• Validated Outcomes: None yet.

6. Active Work State:

• Current Focus: The user is focused on implementing console-log-chalk-security and gantt-ux-improvements.
• Recent Context: The last few exchanges involved delegating tasks to the cloud agent and discussing feature implementations.
• Working Code: No specific code snippets have been discussed recently.
• Immediate Context: The user was addressing the implementation of features before the summary was triggered.

7. Recent Operations:

• Last Agent Commands:
  1. "let's implement console-log-chalk-security"
  2. "@cloud Delegate: 'Delegate to cloud agent'"
  3. "let's implement gantt-ux-improvements as well"
• Tool Results Summary: No specific results were returned as the commands were user requests.
• Pre-Summary State: The agent was actively delegating tasks to the cloud agent when the token budget was exceeded.
• Operation Context: The user is focused on implementing two features, indicating a need for enhanced logging and improved Gantt chart UX.

8. Continuation Plan:

• [Pending Task 1]: Implement console-log-chalk-security - Next steps involve executing the delegation to the cloud agen...

Pull Request Overview

This PR implements UX improvements to the gantt command visualization and adds a package-lock.json file for dependency management. The changes focus on reorganizing the gantt chart display to group specs by priority, simplifying the timeline rendering, and improving the overall layout with better column alignment.

Key Changes:

• Reorganized gantt chart to display specs grouped by priority (critical, high, medium, low)
• Simplified timeline bar rendering to show progress from today to due date
• Updated column layout with consistent widths aligned with stats.ts and timeline.ts
• Added package-lock.json for dependency version locking

[nitpick] The comment states 'Use spec.name instead of spec.path', but this may not provide sufficient context. Consider clarifying why spec.name is preferred over spec.path (e.g., 'Use spec.name for cleaner display without directory path').

Suggested change

	let specName = spec.name; // Use spec.name instead of spec.path
	let specName = spec.name; // Use spec.name for cleaner display without directory path (spec.path includes directories)

Starting all timeline bars from 'today' may be misleading if a spec was created in the past or has already been worked on. Consider whether this simplification accurately represents the spec's actual timeline, especially for in-progress or late-starting specs.

Suggested change

	const specStart = today; // Start from today, not creation date
	// Use the spec's actual start date if available, otherwise fall back to today
	let specStart: dayjs.Dayjs;
	if (spec.frontmatter.start) {
	specStart = dayjs(spec.frontmatter.start);
	} else if (spec.frontmatter.created) {
	specStart = dayjs(spec.frontmatter.created);
	} else {
	specStart = today;
	}

Unused variable timelineColumnWidth.

Suggested change

const timelineColumnWidth = weeks * 8;
