Description

Overhaul GitHub issue templates, add stale bot, and add auto-labeling for issue triage.

Issue templates (O21):

• Rewrote all 4 issue templates as .yml forms with cal.com-style pre-filled markdown (value:) so users see one dropdown + one editable text box
• Bug Report: component dropdown + pre-filled sections (summary, repro steps, expected/actual, environment) + auto-label bug
• Feature Request: component dropdown + pre-filled sections (use case, proposed solution, alternatives) + auto-label enhancement
• Benchmark Submission: pre-filled sections (model, config, dataset, results table, environment) + auto-label benchmark
• Documentation Issue: pre-filled sections (page link, issue, suggested fix) + auto-label documentation
• Updated config.yml contact links from Embedchain to Mem0

Stale bot (O24):

• Runs daily at midnight UTC via GitHub Actions
• Marks issues with no activity for 90 days as stale, auto-closes after 14 more days
• Marks PRs as stale but never auto-closes them
• Exempts P0-critical, P1-high, good first issue, security labels
• Processes 100 issues per run to stay within API limits

Auto-labeler:

• When someone files an issue and picks a component from the dropdown (e.g., "Ollama"), the ollama label is auto-applied via advanced-issue-labeler
• Maps all 9 component dropdown options to matching GitHub labels
• Zero manual triage needed for component labels

Type of Change

• New feature (non-breaking change that adds functionality)

Test Coverage

• No tests needed (explain why)

GitHub Actions workflows and issue templates — tested by verifying YAML syntax and confirming label mappings match existing repo labels.
