[Bug]: JQL reserved words in project keys not automatically quoted

[hteichmann-strato]

Summary

When a Jira project key happens to be a JQL reserved word (e.g. IF), the MCP passes the value unquoted and Jira rejects the query with:

Error in the JQL Query: 'IF' is a reserved JQL word. You must surround it in quotation marks to use it in a query.

Steps to Reproduce

Use jira_search with a JQL query referencing a project whose key is a reserved word:

project = IF AND text ~ "universal-builder" AND issuetype in (Story, Task, Epic) ORDER BY updated DESC

Expected Behavior

The MCP should automatically quote values in project = and project IN (...) positions that are JQL reserved words, producing:

project = "IF" AND text ~ "universal-builder" AND issuetype in (Story, Task, Epic) ORDER BY updated DESC

Actual Behavior

The raw unquoted value is forwarded to the Jira API, which returns an error.

Context

• projects_filter config already quotes project keys correctly (lines 62/64 of search.py)
• The issue only affects raw JQL passed directly via the jql parameter
