Update readme + CLAUDE: -b is no longer SQL-Server-only. Describe the Postgres
COPY FROM STDIN path (CopyManager, text-based, CSV-quoted, empty vs NULL) next
to the existing SQL Server SQLServerBulkCopy path; DB2 still falls back to INSERT.

Add the -b flag to the readme/CLAUDE flag lists and describe the bulk copy
migration sub-mode: SQLServerBulkCopy via the BulkSource adapter (SQL Server
dest only), why numeric/string-ish types route through NVARCHAR, the ~111min
-> ~4min win, and the 10k-row live progress counter.

Reflect the two behavior changes: (1) migration mode sets the source
connection to autoCommit=false so PostgreSQL's setFetchSize actually streams
(it's ignored otherwise) — and why query mode is excluded; (2) json/jsonb/
bpchar/uuid are now quoted, plus document the default-emits-unquoted gotcha
for future type additions.

Clarify that both query and migration modes use streaming with no array
storage. Query mode streams directly to stdout, while migration mode
streams into a SQL string buffer (250 rows). The 10k fetch size is a
JDBC driver hint for network efficiency, not application-level storage.

Changes:
- Rename app/ directory to jrunner/ (preserves git history)
- Update settings.gradle to reference jrunner module
- Update readme.md with new paths (jrunner/build/, /opt/jrunner)
- Update CLAUDE.md documentation with new file paths
Build outputs now named jrunner.zip, jrunner.jar, bin/jrunner instead
of generic "app" names. This makes the project structure clearer and
aligns module name with project name.
