[0.2.0][CI] Add E2E integration test pipeline

[Kavirubc]

Summary

Add an end-to-end integration test pipeline that validates the full Simili Bot triage flow on every PR to main.

Problem

There was no automated way to verify that the bot correctly:

• Posts triage comments on issues
• Detects similar/duplicate issues via vector search
• Applies labels
• Does not enter infinite comment loops

Regressions in any of these areas would only be caught manually.

Solution

A GitHub Actions workflow (.github/workflows/e2e-test.yml) that:

1. Creates a private test repository under the bot user account
2. Seeds it with 5 representative issues and indexes them into a dedicated Qdrant collection
3. Installs the PR version of Simili Bot via the generated triage.yml
4. Creates a trigger issue designed to match the seed issues
5. Polls for the bot's triage comment (similarity detection, duplicate warning, labels)
6. Verifies no infinite loop occurs
7. Cleans up the Qdrant collection (always, even on failure)
8. Posts a result summary comment on the PR

Acceptance Criteria

• E2E workflow passes on every PR to main
• Bot comment is detected within 5 minutes
• Similarity/duplicate detection is verified in the comment body
• Qdrant collection is cleaned up after each run
• Test repository remains private

Quality Improvements

• No explicit non-functional requirements for the test pipeline itself
• Consider adding non-functional requirements for the E2E pipeline (e.g., execution time limits, reliability targets).

Warning

Possible Duplicate (Confidence: 95%)
This issue might be a duplicate of #71.
Reason: Issue #71, titled 'ci: add E2E integration test pipeline', is virtually identical in its request to the current issue, titled '[0.2.0][CI] Add E2E integration test pipeline'. Both describe the exact same feature request: to implement an end-to-end integration test pipeline for the Simili Bot. The detailed solution provided in the current issue would fully resolve the request in Issue #71, indicating the same root cause (lack of automated E2E testing) and the same expected outcome (a functional E2E test pipeline).
