[release-v0.18.x] perf(cli): use exact match for describe/logs command

[divyansh42]

Changes

Cherrypick for #1283
Add GetExactMatch() method to FilterOptions interface to distinguish between exact match filtering (describe/logs) and substring matching (list). This enables faster server-side filtering for operations that query specific resources by name or UID.

Implementation details:

• Added GetExactMatch() to FilterOptions interface
• Updated BuildFilterString() to use exact equality (==) when GetExactMatch() is true, otherwise uses contains() for substring matching
• DescribeOptions and LogsOptions return true for exact matching
• ListOptions returns false to support partial name searches
• Updated command help text to document behavior
• Added test cases covering both list and describe filtering scenarios

When multiple resources match by name, describe/logs commands return the most recent one (ordered by create_time desc). Users can specify
--uid flag to target a specific resource when needed.
