fix: make data table columns terminal-aware

[aidandaly24]

Summary

Make DataTable allocate columns from terminal width so picker tables fill the screen without wrapping or welding adjacent fields.

Changes

• add a pure shrink-then-drop width allocator with structural one-cell column gaps
• add explicit fixed/flex column sizing metadata to all six Runtime and Harness picker configurations
• require an explicit fixed width, default minWidth to it, and keep allocator internals private to DataTable
• represent dropped columns directly through omitted computed widths
• render full version headers and verify every visible production header fits its allocated width
• render compact UTC timestamps and the discriminating Runtime ID suffix
• preserve both rendered-value and raw-value filtering
• use display-cell-aware truncation for Unicode and ANSI-safe output
• remove unreachable interactive sorting inherited from the previous table implementation
• replace the unused @inkui-cli/data-table dependency with direct cli-truncate and string-width dependencies

Validation

• bun install --frozen-lockfile
• bun test (403 passed)
• bun test --coverage --coverage-reporter=lcov
• bun run typecheck
• bun run lint:check
• bun run format:check
• bun run build
• bun audit
• bun pm pack --destination /tmp

Live deploy-profile TUI validation in us-east-1:

• reproduced the base-branch failure at 80 columns: wrapped headers/rows, welded fields, and pagination text overlaid with table data
• verified Runtime list tables exactly fill 60, 80, and 120 columns with one physical line per row
• verified Harness list tables exactly fill 80 columns
• verified filtering by a rendered compact UTC timestamp returns the expected live Runtime row

i like how this cleans up the UI a bit!
