feat: bandarmology (idx stocks bandar, analyze_bandar)

Browse source 
`idx stocks bandar SYMBOL...` reads the broker summary: for the top 1, 3,
5 and 10 brokers per side, buy value minus sell value in basis points of
value traded, with a signal from big accumulation to big distribution on
the headline tier (--top, default 5). Several symbols give a screen ranked
by that figure (at most 100, one request each), which pipes from
`stocks screen`. The MCP server exposes it as analyze_bandar (20 symbols).

- analysis/bandar.rs is pure and versioned (`top_concentration_v1`):
  integer basis points, no figure missing counted as zero, buy/sell VWAP
  from exact averages, and the brokers on both sides listed because their
  gross figures overstate their direction.
- Thresholds (±5%/±15%) follow fzn0x/idx (MIT); docs call them heuristics.
- Invalid input fails a screen at once; other errors fail one symbol and
  are warned about on stderr.

Method top_concentration_v1: the top 3 buyers' value minus the top 3 sellers' value, as a share of value traded; 5% or more reads accumulation, 15% or more big (negative: distribution). Brokers trade for many clients, so this is a heuristic, not advice.

Total 6.6T IDR, average 5,228; foreign net -2.3T (-34.9% of value).
On both sides: AK, CC, MG, XL, YU, ZP; their gross figures overstate which way they traded.
Method top_concentration_v1: the top 5 buyers' value minus the top 5 sellers' value, as a share of value traded; 5% or more reads accumulation, 15% or more big (negative: distribution). Brokers trade for many clients, so this is a heuristic, not advice.
Note: the source rounds figures of a million and more to one decimal.
