MentisDB 0.9.8.44 - Binary Rename, Dashboard Settings, and Dotenvy

0.9.8.44 is a user-experience release: the binary drops its trailing d, the dashboard gains a Settings tab and per-chain storage visibility, and mentisdb now loads configuration from .env files so you can keep project-local settings out of your shell profile.

Breaking change: the installed binary is now mentisdb, not mentisdbd. All documentation, CI artifacts, install scripts, and TUI references have been updated. If you have scripts or aliases that call mentisdbd, update them to mentisdb.

What Changed

Binary rename. mentisdbd → mentisdb. Every reference in docs, tests, CI, install scripts, and the TUI has been updated. cargo install mentisdb produces mentisdb.
Dashboard chain sizes. The Chains table now shows a "Size" column with human-readable on-disk storage (B, KB, MB, GB, TB, PB). A summary bar above the table shows total size, thoughts, agents, and per-index totals across all chains.
Dashboard Settings tab. A new Settings page lists all 18 MENTISDB_* environment variables in a table with type-aware controls (checkbox for booleans, number input for ports, text for strings). Each row shows current value, default, and description. "Reset to Default" per row. "Apply Settings" persists changes to a .env file and hot-reloads auto_flush immediately. Network and storage changes show a restart-required flag.
Dotenvy support. mentisdb loads environment variables from a .env file in the current working directory at startup. Shell env vars take precedence. The file is silently ignored when absent, so you can commit a template .env.example and keep real values in .gitignore-d .env files.
TUI improvements. The Storage Location column now shows chain file size in brackets (e.g. [10 KB] /path/to/chain.tcbin). The running status line now includes the daemon PID so you can identify the process when multiple instances are running.

Verification

Gate	Result
`cargo fmt -- --check`	Passed
`cargo clippy --all-features -- -D warnings`	Passed
`cargo test --all-features`	Passed (257 tests, 80 doc-tests)
GitHub CI	Passed (x86_64/aarch64 macOS, x86_64/aarch64 Linux, Windows)
LoCoMo benchmark	R@10 = 71.80% (single 75.80%, multi 57.20%)

Upgrade

cargo install mentisdb --force

No manual migration is required. Existing chain files, skill registries, and agent identities continue to work unchanged. Scripts that reference mentisdbd should be updated to mentisdb.
