156122: sql/inspect: fix LTREE[] handling in query bounds r=spilchen a=spilchen

INSPECT builds query bounds from primary key column types. When a table had an LTREE[] column, the bound datums could be interpreted as string[] by the query engine, causing errors like:
```
unsupported comparison operator: <ltree[]> >= <string[]>
```

This happened because the datum formatting omitted type information for array elements. For example, ['j.k.l']::LTREE[] was formatted as ARRAY['j.k.l'], which loses the cast. The fix marks the LTREE type as ambiguous so the formatter includes explicit type casts, avoiding mismatches in distributed queries.

While testing, I also added placeholder values to the logged query in inspect issues (previously only the query text was shown).

156183: bootstrap: enable 25.4 mixed-cluster logic tests r=fqazi a=celiala

## bootstrap: enable 25.4 mixed-cluster logic tests

This change enables mixed-cluster logic tests for version 25.4 by adding bootstrap data from release-25.4 and configuring the local-mixed-25.4 test configuration.

### Changes

The bootstrap data was obtained by running (on release-25.4 branch):
```bash
./dev build sql-bootstrap-data && bin/sql-bootstrap-data
```

This PR includes:
- Added bootstrap data files (25_4_system.keys/sha256, 25_4_tenant.keys/sha256)
- Updated initial_values.go with V25_4 mapping
- Added local-mixed-25.4 logictest configuration
- Generated test files for local-mixed-25.4 config
- Updated logictests with skipif directives for local-mixed-25.4
- Added comprehensive runbook at `pkg/clusterversion/CLAUDE.md` documenting the M.2 process

### Documentation

A comprehensive runbook has been added to `pkg/clusterversion/CLAUDE.md` (following the pattern of R.1, R.2, and M.1 runbooks). This documents:
- Step-by-step checklist for future M.2 tasks
- Common errors and solutions
- File locations and patterns
- Testing procedures

This should make future quarterly M.2 tasks easier to execute.

---

Part of M.2 "Enable mixed-cluster logic tests" checklist from https://github.com/cockroachdb/cockroach/blob/master/pkg/clusterversion/README.md

Following the example from previous M.2 work.
